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

       Thesched_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

       Thesched_yield() function shall return 0 if it completes       successfully; otherwise, it shall return a value of -1 and seterrno 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.
