Manual Pages  — POSIX_SPAWNATTR_GETSCHEDPARAM

NAME

posix_spawnattr_getschedparam, posix_spawnattr_setschedparam – get and set the spawn-schedparam attribute of a spawn attributes object

CONTENTS

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.

STANDARDS

The posix_spawnattr_getschedparam() and posix_spawnattr_setschedparam() functions conform to IEEE Std 1003.1-2001 ("POSIX.1").

The most important thing in the programming language is the name. A language will not succeed without a good name. I have recently invented a very good name and now I am looking for a suitable language.
