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.
