.TH io_cancel 2 2002-09-03 "Linux 2.4" "Linux AIO" .SH NAME io_cancel \- Cancel io requests .SH SYNOPSIS .nf .B #include <errno.h> .sp .br .B #include <libaio.h> .sp .br .BI "int io_cancel(io_context_t ctx, struct iocb *iocb)" .br .sp struct iocb { void *data; /* Return in the io completion event */ unsigned key; /* For use in identifying io requests */ short aio_lio_opcode; short aio_reqprio; /* Not used */ int aio_fildes; }; .fi .SH DESCRIPTION Attempts to cancel an iocb previously passed to io_submit. If the operation is successfully cancelled, the resulting event is copied into the memory pointed to by result without being placed into the completion queue. .PP When one or more requests are asynchronously processed, it might be useful in some situations to cancel a selected operation, e.g., if it becomes obvious that the written data is no longer accurate and would have to be overwritten soon. As an example, assume an application, which writes data in files in a situation where new incoming data would have to be written in a file which will be updated by an enqueued request. .SH "RETURN VALUES" 0 is returned on success , otherwise returns Errno. .SH ERRORS .TP .B EFAULT If any of the data structures pointed to are invalid. .TP .B EINVAL If aio_context specified by ctx_id is invalid. .TP .B EAGAIN If the iocb specified was not cancelled. .TP .B ENOSYS if not implemented. .SH "SEE ALSO" .BR io(3), .BR io_fsync(3), .BR io_getevents(3), .BR io_prep_fsync(3), .BR io_prep_pread(3), .BR io_prep_pwrite(3), .BR io_queue_init(3), .BR io_queue_release(3), .BR io_queue_run(3), .BR io_queue_wait(3), .BR io_set_callback(3), .BR io_submit(3), .BR errno(3)
