posix_spawnattr_getschedparam3
Get and set the spawn-schedparam attribute of a spawn attributes object
Usage
#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);
Library
Standard C Library (libc, -lc)
Overview
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.
