Once upon a time I had a book by I believe Jeff Swann on programming in Turbo Pascal 6.0. In the back of the book was and Encyclopedia of the language. Any time I had a problem on a procedure or function I could look it up. It told the syntax, in's and out's and had an example or two of how to use it. It was a GREAT help.
Does such a animal exist for C, inparticular for AVR GCC? Would like to find a public doamin copy but would be worth some real money.
