posix_spawnattr_getschedpStandard)C Library posix_spawnattr_getschedpolicy(3C)NAME
posix_spawnattr_getschedpolicy, posix_spawnattr_setschedpolicy - get
and set spawn-schedpolicy attribute of spawn attributes object
SYNOPSIS
#include <spawn.h>
#include <sched.h>
int posix_spawnattr_getschedpolicy(const posix_spawnattr_t *restrict
attr, int *restrict schedpolicy);
int posix_spawnattr_setschedpolicy(posix_spawnattr_t *attr, int sched‐
policy);
DESCRIPTION
The posix_spawnattr_getschedpolicy() function obtains the value of the
spawn-schedpolicy attribute from the attributes object referenced by
attr.
The posix_spawnattr_setschedpolicy() function sets the spawn-schedpol‐
icy attribute in an initialized attributes object referenced by attr.
The spawn-schedpolicy attribute represents the scheduling policy to be
assigned to the new process image in a spawn operation (if
POSIX_SPAWN_SETSCHEDULER is set in the spawn-flags attribute). The
default value of this attribute is unspecified.
RETURN VALUES
Upon successful completion, posix_spawnattr_getschedpolicy() returns 0
and stores the value of the spawn-schedpolicy attribute of attr into
the object referenced by the schedpolicy parameter. Otherwise, an error
number is returned to indicate the error.
Upon successful completion, posix_spawnattr_setschedpolicy() returns 0.
Otherwise, an error number is returned to indicate the error.
ERRORS
These functions may fail if:
EINVAL The value specified by attr is invalid.
The posix_spawnattr_setschedpolicy() function may fail if:
EINVAL The value of the attribute being set is not valid.
