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_getflags, posix_spawnattr_setflags - get  and  set  the
13       spawn-flags attribute of a spawn attributes object (ADVANCED REALTIME)
14

SYNOPSIS

16       #include <spawn.h>
17
18       int posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr,
19              short *restrict flags);
20       int posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);
21
22

DESCRIPTION

24       The  posix_spawnattr_getflags()  function shall obtain the value of the
25       spawn-flags attribute from the attributes object referenced by attr.
26
27       The  posix_spawnattr_setflags()  function  shall  set  the  spawn-flags
28       attribute in an initialized attributes object referenced by attr.
29
30       The  spawn-flags attribute is used to indicate which process attributes
31       are to be changed in the new process image when invoking  posix_spawn()
32       or  posix_spawnp().  It  is the bitwise-inclusive OR of zero or more of
33       the following flags:
34
35       POSIX_SPAWN_RESETIDS
36       POSIX_SPAWN_SETPGROUP
37       POSIX_SPAWN_SETSIGDEF
38       POSIX_SPAWN_SETSIGMASK
39
40       POSIX_SPAWN_SETSCHEDPARAM
41       POSIX_SPAWN_SETSCHEDULER
42
43
44       These flags are  defined  in  <spawn.h>.  The  default  value  of  this
45       attribute shall be as if no flags were set.
46

RETURN VALUE

48       Upon  successful  completion,  posix_spawnattr_getflags()  shall return
49       zero and store the value of the spawn-flags attribute of attr into  the
50       object  referenced  by  the flags parameter; otherwise, an error number
51       shall be returned to indicate the error.
52
53       Upon successful  completion,  posix_spawnattr_setflags()  shall  return
54       zero;  otherwise,  an  error  number  shall be returned to indicate the
55       error.
56

ERRORS

58       These functions may fail if:
59
60       EINVAL The value specified by attr is invalid.
61
62
63       The posix_spawnattr_setflags() function may fail if:
64
65       EINVAL The value of the attribute being set is not valid.
