posix_spawnattr_getschedpStandard C Library Fposix_spawnattr_getschedparam(3C)NAME
posix_spawnattr_getschedparam, posix_spawnattr_setschedparam - get and
set spawn-schedparam attribute of spawn attributes object
SYNOPSIS
#include <spawn.h>
#include <sched.h>
int posix_spawnattr_getschedparam(const posix_spawnattr_t *restrict
attr, struct sched_param *restrict schedparam);
int posix_spawnattr_setschedparam(posix_spawnattr_t *restrict attr,
const struct sched_param *restrict schedparam);
DESCRIPTION
The posix_spawnattr_getschedparam() function obtains the value of the
spawn-schedparam attribute from the attributes object referenced by
attr.
The posix_spawnattr_setschedparam() function sets the spawn-schedparam
attribute in an initialized attributes object referenced by attr.
The spawn-schedparam attribute represents the scheduling parameters to
be assigned to the new process image in a spawn operation (if
POSIX_SPAWN_SETSCHEDULER or POSIX_SPAWN_SETSCHEDPARAM is set in the
spawn-flags attribute). The default value of this attribute is unspeci‐
fied.
RETURN VALUES
Upon successful completion, posix_spawnattr_getschedparam() returns 0
and stores the value of the spawn-schedparam attribute of attr into the
object referenced by the schedparam parameter. Otherwise, an error num‐
ber is returned to indicate the error.
Upon successful completion, posix_spawnattr_setschedparam() 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_setschedparam() function may fail if:
EINVAL The value of the attribute being set is not valid.
