Description

* This module implements the test sequence for the dynamic thread creation * APIs. * *

Objective

* Objective of the test module is to cover 100% of the dynamic APIs code. * *

Preconditions

* The module requires the following kernel options: * - @p CH_USE_DYNAMIC * - @p CH_USE_HEAP * - @p CH_USE_MEMPOOLS * . * In case some of the required options are not enabled then some or all tests * may be skipped. * *

Test Cases

* - @subpage test_dynamic_001 * - @subpage test_dynamic_002 * - @subpage test_dynamic_003 * . * @file testdyn.c * @brief Dynamic thread APIs test source file * @file testdyn.h * @brief Dynamic thread APIs test header file */ #if CH_USE_DYNAMIC || defined(__DOXYGEN__) #if (CH_USE_HEAP && !CH_USE_MALLOC_HEAP) || defined(__DOXYGEN__) static MemoryHeap heap1; #endif #if CH_USE_MEMPOOLS || defined(__DOXYGEN__) static MemoryPool mp1; #endif /** * @page test_dynamic_001 Threads creation from Memory Heap * *

Description
