qthread_yield - release the CPU, allow other qthreads to run
#include
<qthread/qthread.h>
void
qthread_yield(qthread_t *me);
This function allows a qthread
to explicitly interrupt computation and give other qthreads the chance
to execute even though it has not blocked. This can be useful for things
like busy-waits or cooperative multitasking. Without using this function,
there is no guarantee that other qthreads will have a chance to execute
until the currently running qthread performs a synchronization operation.
The argument, me, should be a pointer to the qthread_t structure for the
currently running qthread, or NULL. If me is NULL, the qthread_t pointer
will be looked up via qthread_self(). If this function is called from a
non-qthread or before the qthread_init() has been run, it does nothing.
