Check if file exists

[Joseph Martin]

Hello,
        I am a little bit of a programming newbie. That is I know the
syntax, but not all the library routines available. Could anyone tell me
how to check if a file exists? Do I open the file and see if it returns
valid or NULL or is there a function that will check for me.

Thanks a bunch,

Joseph Martin
