NAME

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.

STANDARDS

The posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).

HISTORY

The posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() functions first appeared in FreeBSD 8.0.
