Function Documentation

◆ qurt_thread_set_priority()

int qurt_thread_set_priority	(	qurt_thread_t	threadid,
		unsigned short	newprio
	)

◆ qurt_thread_create()

int qurt_thread_create	(	qurt_thread_t *	thread_id,
		qurt_thread_attr_t *	attr,
		void()(void )	entrypoint,
		void *	arg
	)

◆ qurt_thread_join()

int qurt_thread_join	(	unsigned int	tid,
		int *	status
	)

Waits for a specified thread to finish.

The specified thread should be another thread within the same process. The caller thread is suspended until the specified thread exits. When this happens the caller thread is awakened.

Note: If the specified thread has already exited, this function returns immediately with the result value QURT_ENOTHREAD.

Note: Two threads cannot call qurt_thread_join to wait for the same thread to finish. If this happens QuRT generates an exception.

Parameters

[in]	tid	Thread identifier.
[out]	status	Destination variable for thread exit status. Returns an application-defined value indicating the termination status of the specified thread.

Returns: QURT_ENOTHREAD – Thread has already exited.
QURT_EOK – Thread successfully joined with valid status value.
