NAME

       posix_spawn_file_actions_adddup2 - add dup2 action to spawn file actions object

SYNOPSIS

       #include <spawn.h>

       int posix_spawn_file_actions_adddup2(posix_spawn_file_actions_t *file_actions, int fildes, int newfildes);

DESCRIPTION

       The  posix_spawn_file_actions_adddup2()	function  adds	a  dup2(3C)  action  to the object referenced by file_actions that causes the file
       descriptor fildes to be duplicated as newfildes (as if dup2(fildes, newfildes) had been called) when a new process is  spawned  using  this
       file actions object.

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

RETURN VALUES

       Upon  successful  completion, the posix_spawn_file_actions_adddup2() function returns 0. Otherwise, an error number is be returned to indi-
       cate the error.

ERRORS

       The posix_spawn_file_actions_adddup2() function will fail if:

       EBADF	       The value specified by fildes or newfildes is negative or greater than or equal to {OPEN_MAX}.

       ENOMEM	       Insufficient memory exists to add to the spawn file actions object.

       The posix_spawn_file_actions_adddup2() function may fail if:

       EINVAL	       The value specified by file_actions is invalid.

       It is not considered an error for the fildes argument passed to posix_spawn_file_actions_adddup2() to specify a file descriptor	for  which
       the  specified  operation  could not be performed at the time of the call. Any such error will be detected when the associated file actions
       object is later used during a posix_spawn(3C) or posix_spawnp(3C) operation.
