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 inposix_spawn_file_actions_addclose(3C).

if: EBADF The value specified by fildes or newfildes isnegative or greater than or equal to {OPEN_MAX}.
