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

13       posix_spawnattr_getpgroup, posix_spawnattr_setpgroup — get and set  the
14       spawn-pgroup attribute of a spawn attributes object (ADVANCED REALTIME)
15

SYNOPSIS

17       #include <spawn.h>
18
19       int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr,
20           pid_t *restrict pgroup);
21       int posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);
22

DESCRIPTION

24       The  posix_spawnattr_getpgroup() function shall obtain the value of the
25       spawn-pgroup attribute from the attributes object referenced by attr.
26
27       The posix_spawnattr_setpgroup() function  shall  set  the  spawn-pgroup
28       attribute in an initialized attributes object referenced by attr.
29
30       The spawn-pgroup attribute represents the process group to be joined by
31       the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP is
32       set  in the spawn-flags attribute). The default value of this attribute
33       shall be zero.
34

RETURN VALUE

36       Upon successful completion,  posix_spawnattr_getpgroup()  shall  return
37       zero and store the value of the spawn-pgroup attribute of attr into the
38       object referenced by the pgroup parameter; otherwise, an  error  number
39       shall be returned to indicate the error.
40
41       Upon  successful  completion,  posix_spawnattr_setpgroup() shall return
42       zero; otherwise, an error number shall  be  returned  to  indicate  the
43       error.
44

ERRORS

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