Hi Guys, Maybe a silly question ! I have around 7500 "dot h" files on my Open Suse Linux box. Many of them zero size and marked "inaccessible" ! But many of those ".h files" are referenced in "C" programs because they contain functions required by the program. How do I find a needed function ? For instance "peekb()" & "pokeb()" -- Best Regards: Derrick.
