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

DESCRIPTION

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

RETURN VALUE

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

ERRORS

55       These functions may fail if:
56
57       EINVAL The value specified by attr is invalid.
58
59       The posix_spawnattr_setflags() function may fail if:
60
61       EINVAL The value of the attribute being set is not valid.
