POSIX_SPAWNATTR_GETFLAGS(3)

NAME
posix_spawnattr_getflags, posix_spawnattr_setflags - get and set the spawn-flags attribute of a spawn attributes object

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
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.
