PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       posix_spawnattr_getpgroup, posix_spawnattr_setpgroup — get and set  the
13       spawn-pgroup attribute of a spawn attributes object (ADVANCED REALTIME)
14

SYNOPSIS

16       #include <spawn.h>
17
18       int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr,
19           pid_t *restrict pgroup);
20       int posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);
21

DESCRIPTION

23       The  posix_spawnattr_getpgroup() function shall obtain the value of the
24       spawn-pgroup attribute from the attributes object referenced by attr.
25
26       The posix_spawnattr_setpgroup() function  shall  set  the  spawn-pgroup
27       attribute in an initialized attributes object referenced by attr.
28
29       The spawn-pgroup attribute represents the process group to be joined by
30       the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP is
31       set  in the spawn-flags attribute). The default value of this attribute
32       shall be zero.
33

RETURN VALUE

35       Upon successful completion,  posix_spawnattr_getpgroup()  shall  return
36       zero and store the value of the spawn-pgroup attribute of attr into the
37       object referenced by the pgroup parameter; otherwise, an  error  number
38       shall be returned to indicate the error.
39
40       Upon  successful  completion,  posix_spawnattr_setpgroup() shall return
41       zero; otherwise, an error number shall  be  returned  to  indicate  the
42       error.
43

ERRORS

45       These functions may fail if:
46
47       EINVAL The value specified by attr is invalid.
48
49       The posix_spawnattr_setpgroup() function may fail if:
50
51       EINVAL The value of the attribute being set is not valid.
