NAME
posix_spawnattr_init,
posix_spawnattr_destroy —
create and destroy posix_spawn
attributes object
SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_init(posix_spawnattr_t
*attr);
int
posix_spawnattr_destroy(posix_spawnattr_t
*attr);
DESCRIPTION
posix_spawn(3) attributes objects can be initialized by
posix_spawnattr_init()
and destroyed by posix_spawnattr_destroy().
Initialization fills an attributes object pointed by attr with the default values for all the attributes.
Multiple initialization of the same object is undefined behavior and will lead to memory leaks.
Similarly, objects should be passed
to
posix_spawnattr_destroy()
to reclaim memory. The object should not be re-used after destruction. It
can however be initialized again with
posix_spawnattr_init().
An attributes object, possibly modified by
posix_spawn_set*(),
is used to specify what process attributes will be passed across a spawn
operation as implemented by
posix_spawn()
or
posix_spawnp().
Attribute details are described in posix_spawnattr_setflags(3).
Modifying or destroying attributes object will not affect processes that have already been spawned.
RETURN VALUES
These function return 0 on successful completion. They may return
ENOMEM when running out of memory.
