NAME

posix_spawnattr_getschedpolicy, posix_spawnattr_setschedpolicy — get and set the spawn-schedpolicy attribute of a spawn attributes object

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <spawn.h>

int
posix_spawnattr_getschedpolicy(const posix_spawnattr_t *restrict attr, int *restrict schedpolicy);

int
posix_spawnattr_setschedpolicy(posix_spawnattr_t *attr, int schedpolicy);

DESCRIPTION

The posix_spawnattr_getschedpolicy() function obtains the value of the spawn-schedpolicy attribute from the attributes object referenced by attr.

The posix_spawnattr_setschedpolicy() function sets the spawn-schedpolicy attribute in an initialized attributes object referenced by attr.

The spawn-schedpolicy attribute represents the scheduling policy to be assigned to the new process image in a spawn operation (if POSIX_SPAWN_SETSCHEDULER is set in the spawn-flags attribute). The default value of this attribute is unspecified.

RETURN VALUES

The posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() functions return zero.
