qurt_thread_attr_t

typedef struct _qurt_thread_attr qurt_thread_attr_t

Thread attributes.

qurt_mutex_t

Function Documentation

qurt_thread_set_priority()

int qurt_thread_set_priority ( qurt_thread_t threadid, unsigned short newprio )

extern

qurt_thread_create()

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

extern

qurt_thread_join()

int qurt_thread_join ( unsigned int tid, int * status )

extern

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.
