No. The reason being that in Unix 'ls' findng no files is
NOT an error. 'ls' simply reports, quite accurately, the contents
of a directory, if it's empty 'ls' returns am empty list! That's
not an error. 'ls' will return an error if you ask it to list
the contents of a non existent directory however.
In that case the errno() stuff might be useful to you...
