.Fn posix_spawn_file_actions_destroy "posix_spawn_file_actions_t * file_actions"
function initialize the object referenced by
to contain no file actions for
.Fn posix_spawnp .
Initializing an already initialized spawn file actions object may cause
memory to be leaked.
function destroy the object referenced by
.Fa file_actions ;
the object becomes, in effect, uninitialized.
A destroyed spawn file actions object can be reinitialized using
.Fn posix_spawn_file_actions_init .
The object should not be used after it has been destroyed.
.Sh RETURN VALUES
Upon successful completion, these functions return zero;
otherwise, an error number is returned to indicate the error.
function will fail if:
.Bl -tag -width Er
.It Bq Er ENOMEM
Insufficient memory exists to initialize the spawn file actions object.
