NAME
posix_spawnattr_getschedparam,
posix_spawnattr_setschedparam —
get
and set the spawn-schedparam attribute of a spawn attributes object
LIBRARY
Standard C Library (libc, -lc)
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
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 unspecified.
RETURN VALUES
The
posix_spawnattr_getschedparam() and
posix_spawnattr_setschedparam() functions return zero.
