Usage
#include <spawn.h>

posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr, pid_t *restrict pgroup);
int
posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);
Library
Standard C Library (libc, -lc)
Overview
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.
