SCHED_YIELD(3P)           POSIX Programmer's Manual          SCHED_YIELD(3P)

PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

NAME         top

       sched_yield — yield the processor

SYNOPSIS         top

       #include <sched.h>
       int sched_yield(void);

DESCRIPTION         top

       The sched_yield() function shall force the running thread to
       relinquish the processor until it again becomes the head of its
       thread list. It takes no arguments.

RETURN VALUE         top

       The sched_yield() function shall return 0 if it completes
       successfully; otherwise, it shall return a value of −1 and set errno
       to indicate the error.

ERRORS         top

       No errors are defined.
       The following sections are informative.

EXAMPLES         top

       None.

APPLICATION USAGE         top

       The conceptual model for scheduling semantics in POSIX.1‐2008 defines
       a set of thread lists. This set of thread lists is always present
       regardless of the scheduling options supported by the system. On a
       system where the Process Scheduling option is not supported, portable
       applications should not make any assumptions regarding whether
       threads from other processes will be on the same thread list.

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
