POSIX_SPAWN_FILE_ACTIONS_ADDCLOSEFROM_NP(3C) Standard C Library Functions
posix_spawn_file_actions_addclosefrom_np - add closefrom action to
spawn file actions object
Standard C Library (libc, -lc)
#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:
EINVAL The value specified by file_actions is invalid.
ENOMEM Insufficient memory exists to add to the spawn file
actions object.
