* Name: posix_spawn_file_actions_destroy
|
|
*
|
|
* Description:
|
|
* The posix_spawn_file_actions_destroy() function destroys the object
|
|
* referenced by file_actions which was previously initializeed by
|
|
* posix_spawn_file_actions_init(), returning any resources obtained at the
|
|
* time of initialization to the system for subsequent reuse. A
|
|
* posix_spawn_file_actions_t may be reinitialized after having been
|
|
* destroyed, but must not be reused after destruction, unless it has been
|
|
* reinitialized.
|
|
*
|
|
* Input Parameters:
|
|
* file_actions - The posix_spawn_file_actions_t to be destroyed.
|
|
*
|
|
* Returned Value:
|
|
* On success, these functions return 0; on failure they return an error
|
|
* number from <errno.h>.
