#include <spawn.h>
int posix_spawn_file_actions_addclosefrom_np(


     posix_spawn_file_actions_t *file_actions, int lowfildes);

The posix_spawn_file_actions_addclosefrom_np() function adds a closefrom action to the object referenced by file_actions that causes all open file descriptors greater than or equal to lowfildes to be closed when a new process is spawned using this file actions object (see closefrom(3C)).

A spawn file actions object is as defined in posix_spawn_file_actions_addclose(3C).

Upon successful completion, the posix_spawn_file_actions_addclosefrom_np() function returns 0. Otherwise, an error number is returned to indicate the error.

The posix_spawn_file_actions_addclosefrom_np() function will fail if:

EBADF

The value specified by lowfildes is negative.

The posix_spawn_file_actions_addclosefrom_np() function may fail if:
