-+ * only the MACRO names being prefixed with DWC_. This is because a few of

-+
-+/*
-+ * This file defines five types of data structures: singly-linked lists,
-+ * lists, simple queues, tail queues, and circular queues.
-+ *
-+ *
-+ * A singly-linked list is headed by a single forward pointer. The elements
-+ * are singly linked for minimum space and pointer manipulation overhead at
-+ * the expense of O(n) removal for arbitrary elements. New elements can be
-+ * added to the list after an existing element or at the head of the list.
-+ * Elements being removed from the head of the list should use the explicit
-+ * macro for this purpose for optimum efficiency. A singly-linked list may
-+ * only be traversed in the forward direction. Singly-linked lists are ideal
-+ * for applications with large datasets and few or no removals or for
-+ * implementing a LIFO queue.
-+ *
-+ * A list is headed by a single forward pointer (or an array of forward
-+ * pointers for a hash table header). The elements are doubly linked
-+ * so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before
-+ * or after an existing element or at the head of the list. A list
-+ * may only be traversed in the forward direction.
-+ *
-+ * A simple queue is headed by a pair of pointers, one the head of the
-+ * list and the other to the tail of the list. The elements are singly
-+ * linked to save space, so elements can only be removed from the
-+ * head of the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the
-+ * list. A simple queue may only be traversed in the forward direction.
-+ *
-+ * A tail queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or
-+ * after an existing element, at the head of the list, or at the end of
-+ * the list. A tail queue may be traversed in either direction.
-+ *
-+ * A circle queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the list.
-+ * A circle queue may be traversed in either direction, but has a more
-+ * complex end of list detection.
-+ *
-+ * For details on the use of these macros, see the queue(3) manual page.

-+/** @file
-+ *
-+ * A simple implementation of the Observer pattern. Any "module" can
-+ * register as an observer or notifier. The notion of "module" is abstract and
-+ * can mean anything used to identify either an observer or notifier. Usually
-+ * it will be a pointer to a data structure which contains some state, ie an
-+ * object.
-+ *
-+ * Before any notifiers can be added, the global notification manager must be
-+ * brought up with dwc_alloc_notification_manager().
-+ * dwc_free_notification_manager() will bring it down and free all resources.
-+ * These would typically be called upon module load and unload. The
-+ * notification manager is a single global instance that handles all registered
-+ * observable modules and observers so this should be done only once.
-+ *
-+ * A module can be observable by using Notifications to publicize some general
-+ * information about it's state or operation. It does not care who listens, or
-+ * even if anyone listens, or what they do with the information. The observable
-+ * modules do not need to know any information about it's observers or their
-+ * interface, or their state or data.
-+ *
-+ * Any module can register to emit Notifications. It should publish a list of
-+ * notifications that it can emit and their behavior, such as when they will get
-+ * triggered, and what information will be provided to the observer. Then it
-+ * should register itself as an observable module. See dwc_register_notifier().
-+ *
-+ * Any module can observe any observable, registered module, provided it has a
-+ * handle to the other module and knows what notifications to observe. See
-+ * dwc_add_observer().
-+ *
-+ * A function of type dwc_notifier_callback_t is called whenever a notification
-+ * is triggered with one or more observers observing it. This function is
-+ * called in it's own process so it may sleep or block if needed. It is
-+ * guaranteed to be called sometime after the notification has occurred and will
-+ * be called once per each time the notification is triggered. It will NOT be
-+ * called in the same process context used to trigger the notification.
-+ *
-+ * @section Limitiations
-+ *
-+ * Keep in mind that Notifications that can be triggered in rapid sucession may
-+ * schedule too many processes too handle. Be aware of this limitation when
-+ * designing to use notifications, and only add notifications for appropriate
-+ * observable information.
-+ *
-+ * Also Notification callbacks are not synchronous. If you need to synchronize
-+ * the behavior between module/observer you must use other means. And perhaps
-+ * that will mean Notifications are not the proper solution.

-+/** @mainpage DWC Portability and Common Library
-+ *
-+ * This is the documentation for the DWC Portability and Common Library.
-+ *
-+ * @section intro Introduction
-+ *
-+ * The DWC Portability library consists of wrapper calls and data structures to
-+ * all low-level functions which are typically provided by the OS. The WUDEV
-+ * driver uses only these functions. In order to port the WUDEV driver, only
-+ * the functions in this library need to be re-implemented, with the same
-+ * behavior as documented here.
-+ *
-+ * The Common library consists of higher level functions, which rely only on
-+ * calling the functions from the DWC Portability library. These common
-+ * routines are shared across modules. Some of the common libraries need to be
-+ * used directly by the driver programmer when porting WUDEV. Such as the
-+ * parameter and notification libraries.
-+ *
-+ * @section low Portability Library OS Wrapper Functions
-+ *
-+ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
-+ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC(). All of
-+ * these functions are included in the dwc_os.h file.
-+ *
-+ * There are many functions here covering a wide array of OS services. Please
-+ * see dwc_os.h for details, and implementation notes for each function.
-+ *
-+ * @section common Common Library Functions
-+ *
-+ * Any function starting with dwc and in all lowercase is a common library
-+ * routine. These functions have a portable implementation and do not need to
-+ * be reimplemented when porting. The common routines can be used by any
-+ * driver, and some must be used by the end user to control the drivers. For
-+ * example, you must use the Parameter common library in order to set the
-+ * parameters in the WUDEV module.
-+ *
-+ * The common libraries consist of the following:
-+ *
-+ * - Connection Contexts - Used internally and can be used by end-user. See dwc_cc.h
-+ * - Parameters - Used internally and can be used by end-user. See dwc_params.h
-+ * - Notifications - Used internally and can be used by end-user. See dwc_notifier.h
-+ * - Lists - Used internally and can be used by end-user. See dwc_list.h
-+ * - Memory Debugging - Used internally and can be used by end-user. See dwc_os.h
-+ * - Modpow - Used internally only. See dwc_modpow.h
-+ * - DH - Used internally only. See dwc_dh.h
-+ * - Crypto - Used internally only. See dwc_crypto.h
-+ *
-+ *
-+ * @section prereq Prerequistes For dwc_os.h
-+ * @subsection types Data Types
-+ *
-+ * The dwc_os.h file assumes that several low-level data types are pre defined for the
-+ * compilation environment. These data types are:
-+ *
-+ * - uint8_t - unsigned 8-bit data type
-+ * - int8_t - signed 8-bit data type
-+ * - uint16_t - unsigned 16-bit data type
-+ * - int16_t - signed 16-bit data type
-+ * - uint32_t - unsigned 32-bit data type
-+ * - int32_t - signed 32-bit data type
-+ * - uint64_t - unsigned 64-bit data type
-+ * - int64_t - signed 64-bit data type
-+ *
-+ * Ensure that these are defined before using dwc_os.h. The easiest way to do
-+ * that is to modify the top of the file to include the appropriate header.
-+ * This is already done for the Linux environment. If the DWC_LINUX macro is
-+ * defined, the correct header will be added. A standard header <stdint.h> is
-+ * also used for environments where standard C headers are available.
-+ *
-+ * @subsection stdarg Variable Arguments
-+ *
-+ * Variable arguments are provided by a standard C header <stdarg.h>. it is
-+ * available in Both the Linux and ANSI C enviornment. An equivalent must be
-+ * provided in your enviornment in order to use dwc_os.h with the debug and
-+ * tracing message functionality.
-+ *
-+ * @subsection thread Threading
-+ *
-+ * WUDEV Core must be run on an operating system that provides for multiple
-+ * threads/processes. Threading can be implemented in many ways, even in
-+ * embedded systems without an operating system. At the bare minimum, the
-+ * system should be able to start any number of processes at any time to handle
-+ * special work. It need not be a pre-emptive system. Process context can
-+ * change upon a call to a blocking function. The hardware interrupt context
-+ * that calls the module's ISR() function must be differentiable from process
-+ * context, even if your processes are impemented via a hardware interrupt.
-+ * Further locking mechanism between process must exist (or be implemented), and
-+ * process context must have a way to disable interrupts for a period of time to
-+ * lock them out. If all of this exists, the functions in dwc_os.h related to
-+ * threading should be able to be implemented with the defined behavior.
-+ *

-+ * buflen=N default N=4096, buffer size used
-+ * qlen=N default N=32, how many buffers in the loopback queue
-+ * loopdefault default false, list loopback config first

-+ * The Core Interface Layer provides basic services for accessing and
-+ * managing the DWC_otg hardware. These services are used by both the
-+ * Host Controller Driver and the Peripheral Controller Driver.
-+ *
-+ * The CIL manages the memory map for the core so that the HCD and PCD
-+ * don't have to do this separately. It also handles basic tasks like
-+ * reading/writing the registers and data FIFOs in the controller.
-+ * Some of the data access functions provide encapsulation of several
-+ * operations required to perform a task, such as writing multiple
-+ * registers to start a transfer. Finally, the CIL performs basic
-+ * services that are not specific to either the host or device modes
-+ * of operation. These services include management of the OTG Host
-+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
-+ * Diagnostic API is also provided to allow testing of the controller
-+ * hardware.
-+ *
-+ * The Core Interface Layer has the following requirements:
-+ * - Provides basic controller operations.
-+ * - Minimal use of OS services.
-+ * - The OS services used will be abstracted by using inline functions
-+ * or macros.

-+/** @file
-+ * The dwc_otg_driver module provides the initialization and cleanup entry
-+ * points for the DWC_otg driver. This module will be dynamically installed
-+ * after Linux is booted using the insmod command. When the module is
-+ * installed, the dwc_otg_driver_init function is called. When the module is
-+ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
-+ *
-+ * This module also defines a data structure for the dwc_otg_driver, which is
-+ * used in conjunction with the standard ARM lm_device structure. These
-+ * structures allow the OTG driver to comply with the standard Linux driver
-+ * model in which devices and drivers are registered with a bus driver. This
-+ * has the benefit that Linux can expose attributes of the driver and device
-+ * in its special sysfs file system. Users can then read or write files in
-+ * this file system to perform diagnostics on the driver components or the
-+ * device.

-+ * This file contains the data structures for accessing the DWC_otg core registers.
-+ *
-+ * The application interfaces with the HS OTG core by reading from and
-+ * writing to the Control and Status Register (CSR) space through the
-+ * AHB Slave interface. These registers are 32 bits wide, and the
-+ * addresses are 32-bit-block aligned.
-+ * CSRs are classified as follows:
-+ * - Core Global Registers
-+ * - Device Mode Registers
-+ * - Device Global Registers
-+ * - Device Endpoint Specific Registers
-+ * - Host Mode Registers
-+ * - Host Global Registers
-+ * - Host Port CSRs
-+ * - Host Channel Specific Registers
-+ *
-+ * Only the Core Global registers can be accessed in both Device and
-+ * Host modes. When the HS OTG core is operating in one mode, either
-+ * Device or Host, the application must not access registers from the
-+ * other mode. When the core switches from one mode to another, the
-+ * registers in the new mode of operation must be reprogrammed as they
-+ * would be after a power-on reset.

-+ 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
-+ multiplies two USItype integers MULTIPLER and MULTIPLICAND,
-+ and generates a two-part USItype product in HIGH_PROD and
-+ LOW_PROD.
-+
-+ 2) __umulsidi3(a,b) multiplies two USItype integers A and B,
-+ and returns a UDItype product. This is just a variant of umul_ppmm.
-+
-+ 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-+ denominator) divides a two-word unsigned integer, composed by the
-+ integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
-+ places the quotient in QUOTIENT and the remainder in REMAINDER.
-+ HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
-+ If, in addition, the most significant bit of DENOMINATOR must be 1,
-+ then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-+
-+ 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-+ denominator). Like udiv_qrnnd but the numbers are signed. The
-+ quotient is rounded towards 0.
-+
-+ 5) count_leading_zeros(count, x) counts the number of zero-bits from
-+ the msb to the first non-zero bit. This is the number of steps X
-+ needs to be shifted left to set the msb. Undefined for X == 0.
-+
-+ 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
-+ high_addend_2, low_addend_2) adds two two-word unsigned integers,
-+ composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
-+ LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
-+ LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
-+ lost.
-+
-+ 7) sub_ddmmss(high_difference, low_difference, high_minuend,
-+ low_minuend, high_subtrahend, low_subtrahend) subtracts two
-+ two-word unsigned integers, composed by HIGH_MINUEND_1 and
-+ LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
-+ respectively. The result is placed in HIGH_DIFFERENCE and

-+ 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
-+ multiplies two USItype integers MULTIPLER and MULTIPLICAND,

-+
-+ 2) __umulsidi3(a,b) multiplies two USItype integers A and B,
-+ and returns a UDItype product. This is just a variant of umul_ppmm.
-+
-+ 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-+ denominator) divides a two-word unsigned integer, composed by the
-+ integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
-+ places the quotient in QUOTIENT and the remainder in REMAINDER.
-+ HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
-+ If, in addition, the most significant bit of DENOMINATOR must be 1,
-+ then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-+

-+
-+ 5) count_leading_zeros(count, x) counts the number of zero-bits from

-+/**
-+ * \mainpage OS Abstraction Layer
-+ *
-+ * \section intro Introduction
-+ *
-+ * This abstraction layer is here to allow the underlying OS to be easily changed (e.g. from
-+ * Nucleus to ThreadX) and to aid in porting host applications to new targets.
-+ *
-+ * \subsection error Error handling
-+ *
-+ * Wherever possible, VCOS functions assert internally and return void. The only exceptions
-+ * are creation functions (which might fail due to lack of resources) and functions that
-+ * might timeout or fail due to lack of space. Errors that might be reported by the underlying
-+ * OS API (e.g. invalid mutex) are treated as a programming error, and are merely asserted on.
-+ *
-+ * \section thread_synch Threads and synchronisation
-+ *
-+ * \subsection thread Threads
-+ *
-+ * The thread API is somewhat different to that found in Nucleus. In particular, threads
-+ * cannot just be destroyed at arbitrary times and nor can they merely exit. This is so
-+ * that the same API can be implemented across all interesting platforms without too much
-+ * difficulty. See vcos_thread.h for details. Thread attributes are configured via
-+ * the VCOS_THREAD_ATTR_T structure, found in vcos_thread_attr.h.
-+ *
-+ * \subsection sema Semaphores
-+ *
-+ * Counted semaphores (c.f. Nucleus NU_SEMAPHORE) are created with VCOS_SEMAPHORE_T.
-+ * Under ThreadX on VideoCore, semaphores are implemented using VideoCore spinlocks, and
-+ * so are quite a lot faster than ordinary ThreadX semaphores. See vcos_semaphore.h.
-+ *
-+ * \subsection mtx Mutexes
-+ *
-+ * Mutexes are used for locking. Attempts to take a mutex twice, or to unlock it
-+ * in a different thread to the one in which it was locked should be expected to fail.
-+ * Mutexes are not re-entrant (see vcos_reentrant_mutex.h for a slightly slower
-+ * re-entrant mutex).
-+ *
-+ * \subsection evflags Event flags
-+ *
-+ * Event flags (the ThreadX name - also known as event groups under Nucleus) provide
-+ * 32 flags which can be waited on by multiple clients, and signalled by multiple clients.
-+ * A timeout can be specified. See vcos_event_flags.h. An alternative to this is the
-+ * VCOS_EVENT_T (see vcos_event.h) which is akin to the Win32 auto-reset event, or a
-+ * saturating counted semaphore.
-+ *
-+ * \subsection event Events
-+ *
-+ * A VCOS_EVENT_T is a bit like a saturating semaphore. No matter how many times it
-+ * is signalled, the waiter will only wake up once. See vcos_event.h. You might think this
-+ * is useful if you suspect that the cost of reading the semaphore count (perhaps via a
-+ * system call) is expensive on your platform.
-+ *
-+ * \subsection tls Thread local storage
-+ *
-+ * Thread local storage is supported using vcos_tls.h. This is emulated on Nucleus
-+ * and ThreadX.
-+ *
-+ * \section int Interrupts
-+ *
-+ * The legacy LISR/HISR scheme found in Nucleus is supported via the legacy ISR API,
-+ * which is also supported on ThreadX. New code should avoid this, and old code should
-+ * be migrated away from it, since it is slow. See vcos_legacy_isr.h.
-+ *
-+ * Registering an interrupt handler, and disabling/restoring interrupts, is handled
-+ * using the functions in vcos_isr.h.
-+ *
-+ */
-+
-+/**
-+ * \file vcos.h
-+ *
-+ * This is the top level header file. Clients include this. It pulls in the platform-specific
-+ * header file (vcos_platform.h) together with header files defining the expected APIs, such
-+ * as vcos_mutex.h, vcos_semaphore.h, etc. It is also possible to include these header files
-+ * directly.

-+#define VCOS_ASSERT_H
-+
-+/*
-+ * Macro:
-+ * vcos_assert(cond)
-+ * vcos_assert_msg(cond, fmt, ...)
-+ * Use:
-+ * Detecting programming errors by ensuring that assumptions are correct.
-+ * On failure:
-+ * Performs a platform-dependent "breakpoint", usually with an assert-style
-+ * message. The '_msg' variant expects a printf-style format string and
-+ * parameters.
-+ * If a failure is detected, the code should be fixed and rebuilt.
-+ * In release builds:
-+ * Generates no code, i.e. does not evaluate 'cond'.
-+ * Returns:
-+ * Nothing.
-+ *
-+ * Macro:
-+ * vcos_demand(cond)
-+ * vcos_demand_msg(cond, fmt, ...)
-+ * Use:
-+ * Detecting fatal system errors that require a reboot.
-+ * On failure:
-+ * Performs a platform-dependent "breakpoint", usually with an assert-style
-+ * message, then calls vcos_abort (see below).
-+ * In release builds:
-+ * Calls vcos_abort() if 'cond' is false.
-+ * Returns:
-+ * Nothing (never, on failure).
-+ *
-+ * Macro:
-+ * vcos_verify(cond)
-+ * vcos_verify_msg(cond, fmt, ...)
-+ * Use:
-+ * Detecting run-time errors and interesting conditions, normally within an
-+ * 'if' statement to catch the failures, i.e.
-+ * if (!vcos_verify(cond)) handle_error();
-+ * On failure:
-+ * Generates a message and optionally stops at a platform-dependent
-+ * "breakpoint" (usually disabled). See vcos_verify_bkpts_enable below.
-+ * In release builds:
-+ * Just evaluates and returns 'cond'.
-+ * Returns:
-+ * Non-zero if 'cond' is true, otherwise zero.
-+ *
-+ * Macro:
-+ * vcos_static_assert(cond)
-+ * Use:
-+ * Detecting compile-time errors.
-+ * On failure:
-+ * Generates a compiler error.
-+ * In release builds:
-+ * Generates a compiler error.
-+ *
-+ * Function:
-+ * void vcos_abort(void)
-+ * Use:
-+ * Invokes the fatal error handling mechanism, alerting the host where
-+ * applicable.
-+ * Returns:
-+ * Never.
-+ *
-+ * Macro:
-+ * VCOS_VERIFY_BKPTS
-+ * Use:
-+ * Define in a module (before including vcos.h) to specify an alternative
-+ * flag to control breakpoints on vcos_verify() failures.
-+ * Returns:
-+ * Non-zero values enable breakpoints.
-+ *
-+ * Function:
-+ * int vcos_verify_bkpts_enable(int enable);
-+ * Use:
-+ * Sets the global flag controlling breakpoints on vcos_verify failures,
-+ * enabling the breakpoints iff 'enable' is non-zero.
-+ * Returns:
-+ * The previous state of the flag.
-+ *
-+ * Function:
-+ * int vcos_verify_bkpts_enabled(void);
-+ * Use:
-+ * Queries the state of the global flag enabling breakpoints on vcos_verify
-+ * failures.
-+ * Returns:
-+ * The current state of the flag.
-+ *
-+ * Examples:
-+ *
-+ * int my_breakpoint_enable_flag = 1;
-+ *
-+ * #define VCOS_VERIFY_BKPTS my_breakpoint_enable_flag
-+ *
-+ * #include "interface/vcos/vcos.h"
-+ *
-+ * vcos_static_assert((sizeof(object) % 32) == 0);
-+ *
-+ * // ...
-+ *
-+ * vcos_assert_msg(postcondition_is_true, "Coding error");
-+ *
-+ * if (!vcos_verify_msg(buf, "Buffer allocation failed (%d bytes)", size))
-+ * {
-+ * // Tidy up
-+ * // ...
-+ * return OUT_OF_MEMORY;
-+ * }
-+ *

-+ *
-+ * On both Nucleus and ThreadX a semaphore can be taken with a timeout. This is
-+ * not supported by VCOS because it makes the non-timeout code considerably more
-+ * complicated (and hence slower). In the unlikely event that you need a timeout
-+ * with a semaphore, and you cannot simply redesign your code to avoid it, use
-+ * an event flag (vcos_event_flags.h).
-+ *
-+ * \subsection sem_nucleus Changes from Nucleus:
-+ *
-+ * Semaphores are always "FIFO" - i.e. sleeping threads are woken in FIFO order. That's
-+ * because:
-+ * \arg there's no support for NU_PRIORITY in threadx (though it can be emulated, slowly)
-+ * \arg we don't appear to actually consciously use it - for example, Dispmanx uses

-+ * \file vcos_thread.h

-+ * \section thread Threads
-+ *
-+ * Under Nucleus, a thread is created by NU_Create_Task, passing in the stack
-+ * and various other parameters. To stop the thread, NU_Terminate_Thread() and
-+ * NU_Delete_Thread() are called.
-+ *
-+ * Unfortunately it's not possible to emulate this API under some fairly common
-+ * operating systems. Under Windows you can't pass in the stack, and you can't
-+ * safely terminate a thread.
-+ *
-+ * Therefore, an API which is similar to the pthreads API is used instead. This
-+ * API can (mostly) be emulated under all interesting operating systems.
-+ *
-+ * Obviously this makes the code somewhat more complicated on VideoCore than it
-+ * would otherwise be - we end up with an extra mutex per thread, and some code
-+ * that waits for it. The benefit is that we have a single way of creating
-+ * threads that works consistently on all platforms (apart from stack supplying).
-+ *
-+ * \subsection stack Stack
-+ *
-+ * It's still not possible to pass in the stack address, but this can be made
-+ * much more obvious in the API: the relevant function is missing and the
-+ * CPP symbol VCOS_CAN_SET_STACK_ADDR is zero rather than one.
-+ *
-+ * \subsection thr_create Creating a thread
-+ *
-+ * The simplest way to create a thread is with vcos_thread_create() passing in a
-+ * NULL thread parameter argument. To wait for the thread to exit, call
-+ * vcos_thread_join().
-+ *
-+ * \subsection back Backward compatibility
-+ *
-+ * To ease migration, a "classic" thread creation API is provided for code
-+ * that used to make use of Nucleus, vcos_thread_create_classic(). The
-+ * arguments are not exactly the same, as the PREEMPT parameter is dropped.
