NAME

pthread_yield - yield the processor

SYNOPSIS

#define _GNU_SOURCE             /* See feature_test_macros(7) */
#include <pthread.h>

int pthread_yield(void);

Compile and link with -pthread.

DESCRIPTION

pthread_yield() causes the calling thread to relinquish the CPU. The thread is placed at the end of the run queue for its static priority and another thread is scheduled to run. For further details, see sched_yield(2)

RETURN VALUE

On success, pthread_yield() returns 0; on error, it returns an error number.

ERRORS

On Linux, this call always succeeds (but portable and future-proof applications should nevertheless handle a possible error return).

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).

Interface	Attribute	Value
pthread_yield()	Thread safety	MT-Safe

CONFORMING TO

This call is nonstandard, but present on several other systems. Use the standardized sched_yield(2) instead.

NOTES

On Linux, this function is implemented as a call to sched_yield(2).
