NAME

posix_spawnattr_getpgroup, posix_spawnattr_setpgroup —

get and set the spawn-pgroup attribute of a spawn attributes object

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <spawn.h>

int
posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr, pid_t *restrict pgroup);

int
posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);

DESCRIPTION

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

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

The spawn-pgroup attribute represents the process group to be joined by the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP is set in the spawn-flags attribute). The default value of this attribute is zero.

RETURN VALUES

The posix_spawnattr_getpgroup() and posix_spawnattr_setpgroup() functions return zero.

STANDARDS

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

HISTORY

The posix_spawnattr_getpgroup() and posix_spawnattr_setpgroup() functions first appeared in FreeBSD 8.0.
