NAME
posix_spawnattr_getpgroup, posix_spawnattr_setpgroup - get and set
spawn-pgroup attribute of spawn attributes object
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
Upon successful completion,
posix_spawnattr_getpgroup() returns 0 and
stores the value of the
spawn-pgroup attribute of
attr into the
object referenced by the
pgroup parameter. Otherwise, an error number
is returned to indicate the error.
Upon successful completion,
posix_spawnattr_setpgroup() returns 0.
Otherwise, an error number is returned to indicate the error.
ERRORS
These functions may fail if:
EINVAL The value specified by
attr is invalid.

posix_spawnattr_setpgroup() function may fail if:
EINVAL The value of the attribute being set is not valid.
