50.Sh DESCRIPTION
51The
52.Fn posix_spawn_file_actions_init
53function initialize the object referenced by
54.Fn file_actions
55to contain no file actions for
56.Fn posix_spawn
57or
58.Fn posix_spawnp .
59Initializing an already initialized spawn file actions object may cause
60memory to be leaked.

63.Fn posix_spawn_file_actions_destroy
64function destroy the object referenced by
65.Fa file_actions ;
66the object becomes, in effect, uninitialized.
67A destroyed spawn file actions object can be reinitialized using
68.Fn posix_spawn_file_actions_init .
69The object should not be used after it has been destroyed.
70.Sh RETURN VALUES
71Upon successful completion, these functions return zero;
72otherwise, an error number is returned to indicate the error.
73.Sh ERRORS
