POSIX_SPAWNATTR_GETPGROUP(P)	    POSIX Programmer's Manual	     POSIX_SPAWNATTR_GETPGROUP(P)

NAME
       posix_spawnattr_getpgroup,  posix_spawnattr_setpgroup  -  get  and  set	the  spawn-pgroup
       attribute of a spawn attributes object (ADVANCED REALTIME)

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  shall	obtain	the  value  of	the  spawn-pgroup
       attribute from the attributes object referenced by attr.

       The  posix_spawnattr_setpgroup()  function shall set the spawn-pgroup attribute in an ini-
       tialized 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 shall be zero.

RETURN VALUE
       Upon successful completion, posix_spawnattr_getpgroup() shall return zero  and  store  the
       value  of  the  spawn-pgroup  attribute	of  attr into the object referenced by the pgroup
       parameter; otherwise, an error number shall be returned to indicate the error.

       Upon successful completion, posix_spawnattr_setpgroup() shall return zero;  otherwise,  an
       error number shall be returned to indicate the error.

ERRORS
       These functions may fail if:

       EINVAL The value specified by attr is invalid.

       The posix_spawnattr_setpgroup() function may fail if:

       EINVAL The value of the attribute being set is not valid.
