This manual page is part of the POSIX Programmer’s Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

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

  #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);

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.

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

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.

None.

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

Refer to the RATIONALE section in /posix_spawn_file_actions_addclose ( )/.

None.
