I am new to programming, so bear with me. I bought a book on learning C and copied a program in my computer. The book states some keywords (i.e. stdprn) may be specific to the compiler. I tried compiling the program but got hung up on the stdprn keyword. I tried looking up the equivalent online, but the manual did not have a friendly index. Is there a webpage that lists the keywords and thier functions specific to my compiler (GCC 4.0.0) that is easy to use and understand? Thanks in advance.
