.TH SCHED_YIELD 2 "15 Septiembre 2017" Linux "Manual del Programador de Linux"
.SH NOMBRE
sched_yield \- cede el procesador
.SH SINOPSIS
\fB#include <sched.h>\fP
.PP
\fBint sched_yield(void);\fP
.SH DESCRIPCIÓN
\fBsched_yield\fP()  causes the calling thread to relinquish the CPU.  The
thread is moved to the end of the queue for its static priority and a new
thread gets to run.
.SH "VALOR DEVUELTO"
En caso de éxito, \fBsched_yield\fP() devuelve 0. En caso de error, se devuelve
\-1 y se pone un valor apropiado en \fIerrno\fP.
.SH ERRORES
In the Linux implementation, \fBsched_yield\fP()  always succeeds.
.SH "CONFORME A"
POSIX.1\-2001, POSIX.1\-2008.
.SH NOTAS
If the calling thread is the only thread in the highest priority list at
that time, it will continue to run after a call to \fBsched_yield\fP().
.PP
En sistemas POSIX donde está disponible \fBsched_yield\fP() se define
\fB_POSIX_PRIORITY_SCHEDULING\fP en \fI<unistd.h>\fP.
.PP
Strategic calls to \fBsched_yield\fP()  can improve performance by giving other
threads or processes a chance to run when (heavily) contended resources
(e.g., mutexes)  have been released by the caller.  Avoid calling
\fBsched_yield\fP()  unnecessarily or inappropriately (e.g., when resources
needed by other schedulable threads are still held by the caller), since
doing so will result in unnecessary context switches, which will degrade
system performance.
.PP
\fBsched_yield\fP()  is intended for use with real\-time scheduling policies
(i.e., \fBSCHED_FIFO\fP or \fBSCHED_RR\fP).  Use of \fBsched_yield\fP()  with
nondeterministic scheduling policies such as \fBSCHED_OTHER\fP is unspecified
and very likely means your application design is broken.
