- * Name: posix_spawn_file_actions_addopen
- *
- * Description:
- *   The posix_spawn_file_actions_addopen() function adds an open 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 fd is opened using
- *   the path, oflag, and mode arguments as if open() had been called on it
- *   prior to the new child process starting execution.  The string path is
- *   copied by the posix_spawn_file_actions_addopen() function during this
- *   process, so storage need not be persistent in the caller.
- *
- * Input Parameters:
- *   file_actions - The posix_spawn_file_actions_t to append the action.
- *   fd - The file descriptor to be opened.
- *   path - The path to be opened.
- *   oflags - Open flags
- *   mode - File creation mode
- *
- * Returned Value:
- *   On success, these functions return 0; on failure they return an error
- *   number from <errno.h>.
