NAME
posix_spawnattr_getflags,
posix_spawnattr_setflags —
get and set the spawn-flags attribute
of a spawn attributes object
LIBRARY
library “libc”
SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_getflags(const
posix_spawnattr_t *restrict attr,
short *restrict
flags);
int
posix_spawnattr_setflags(posix_spawnattr_t
*attr, short
flags);
DESCRIPTION
Theposix_spawnattr_getflags()
function obtains the value of the spawn-flags attribute from the attributes
object referenced by attr.
The
posix_spawnattr_setflags()
function sets the spawn-flags attribute in an initialized attributes object
referenced by attr.
The spawn-flags attribute is used to indicate
which process attributes are to be changed in the new process image when
invoking
posix_spawn()
or
posix_spawnp().
It is the bitwise-inclusive OR of zero or more of the following flags (see
posix_spawn()):
These flags are defined in
<spawn.h>. The default value
of this attribute is as if no flags were set.
RETURN VALUES
The posix_spawnattr_getflags() and
posix_spawnattr_setflags() functions return
zero.

STANDARDS

posix_spawnattr_setflags() functions conform to
IEEE Std 1003.1-2001 (“POSIX.1”).
