Synopsis:

Description:
The posix_spawnattr_destroy() function destroys a spawn attributes object.
A spawn attributes object is an opaque object of type posix_spawnattr_t (defined in
<spawn.h>) that you can use to modify the behavior of
posix_spawn() or posix_spawnp().
Note:
The
posix_spawnattr_destroy() function renders the
posix_spawnattr_t unusable.
Before you can reuse the object, you must initialize it with
posix_spawnattr_init().
POSIX specifies that results are undefined if you use a
posix_spawnattr_t object
after it has been destroyed, including calling
posix_spawnattr_destroy() on an already destroyed object.
If you attempt to reference a destroyed attributes object,
all of the
posix_spawnattr_get*() and
posix_spawnattr_set*() operations, as well as
posix_spawn(), return
EINVAL.
Returns:
- EOK
- Success.
- EINVAL
- The value specified by attrp is invalid.
