NAME

posix_spawnattr_getflags, posix_spawnattr_setflagsget and set the spawn-flags attribute of a spawn attributes object

LIBRARY

Standard C Library (libc, -lc)

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

The posix_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()):

POSIX_SPAWN_RESETIDS
POSIX_SPAWN_SETPGROUP
POSIX_SPAWN_SETSIGDEF
POSIX_SPAWN_SETSIGMASK
POSIX_SPAWN_SETSCHEDPARAM
POSIX_SPAWN_SETSCHEDULER

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

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

HISTORY

The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.0.
