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

NAME
       sched_yield -- yield the processor

SYNOPSIS
       #include <sched.h>

       int sched_yield(void);

DESCRIPTION
       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
       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
       No errors are defined.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       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
       None.

FUTURE DIRECTIONS
       None.
