#### NAME

> posix_spawn_file_actions_destroy, posix_spawn_file_actions_init - destroy and initialize spawn file actions object (ADVANCED REALTIME)

#### SYNOPSIS

> ``[SPN] #include <spawn.h>
> int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t
> *`file_actions`);
> int posix_spawn_file_actions_init(posix_spawn_file_actions_t
> *`file_actions`);``
> `
> `

#### DESCRIPTION

> The posix_spawn_file_actions_destroy() function shall destroy the object referenced by file_actions; the object becomes, in effect, uninitialized. An implementation may cause posix_spawn_file_actions_destroy() to set the object referenced by file_actions to an invalid value. A destroyed spawn file actions object can be reinitialized using posix_spawn_file_actions_init(); the results of otherwise referencing the object after it has been destroyed are undefined.

> The posix_spawn_file_actions_init() function shall initialize the object referenced by file_actions to contain no file actions for posix_spawn() or posix_spawnp() to perform.

> A spawn file actions object is as defined in posix_spawn_file_actions_addclose.

> The effect of initializing an already initialized spawn file actions object is undefined.

#### RETURN VALUE

> Upon successful completion, these functions shall return zero; otherwise, an error number shall be returned to indicate the error.

#### ERRORS

> The posix_spawn_file_actions_init() function shall fail if:

> [ENOMEM]
>   Insufficient memory exists to initialize the spawn file actions object.

> The posix_spawn_file_actions_destroy() function may fail if:

> [EINVAL]
>   The value specified by file_actions is invalid.

The following sections are informative.

#### EXAMPLES

> None.

#### APPLICATION USAGE

> These functions are part of the Spawn option and need not be provided on all implementations.

#### RATIONALE

> Refer to the RATIONALE section in posix_spawn_file_actions_addclose.

#### FUTURE DIRECTIONS

> None.

#### SEE ALSO

> posix_spawn, posix_spawn_file_actions_addclose

> XBD <spawn.h>

#### CHANGE HISTORY

> First released in Issue 6. Derived from IEEE Std 1003.1d-1999.

> In the SYNOPSIS, the inclusion of <sys/types.h> is no longer required.
