- * Name: posix_spawn_file_actions_adddup2
- *
- * Description:
- *   The posix_spawn_file_actions_adddup2() function adds a dup2 operation to
- *   the list of operations associated with the object referenced by
- *   file_actions, for subsequent use in a call to posix_spawn() or
- *   posix_spawnp().  The descriptor referred to by fd2 is created as
- *   if dup2() had been called on fd1 prior to the new child process
- *   starting execution.
- *
- * Input Parameters:
- *   file_actions - The posix_spawn_file_actions_t to append the action.
- *   fd1 - The first file descriptor to be argument to dup2.
- *   fd2 - The first file descriptor to be argument to dup2.
- *
- * Returned Value:
- *   On success, these functions return 0; on failure they return an error
- *   number from <errno.h>.
