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 unspeci‐
fied.
RETURN VALUES
The posix_spawnattr_getschedparam() and posix_spawnattr_setschedparam()
functions return zero.
