NAME
posix_spawnattr_getschedparam,
posix_spawnattr_setschedparam —
get and set the spawn-schedparam
attribute of a spawn attributes object
LIBRARY
library “libc”
SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_getschedparam(const
posix_spawnattr_t *restrict attr,
struct sched_param *restrict
schedparam);
int
posix_spawnattr_setschedparam(posix_spawnattr_t
*attr, const struct
sched_param *restrict schedparam);
DESCRIPTION
Theposix_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 unspecified.
RETURN VALUES
The posix_spawnattr_getschedparam() and
posix_spawnattr_setschedparam() functions return
zero.
