POSIX_SPAWNATTR_GETPGROUP(3P)                       POSIX Programmer's Manual                      POSIX_SPAWNATTR_GETPGROUP(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

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 initialized attributes object refer-
       enced 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.

APPLICATION USAGE
