I'm having trouble doing the following:

I have a string within elisp like "main.c" and I want to 
search for it in a file, so I want to convert it to "main\.c"
so that it matches exactly - but how to modify the string from
within elisp?

Do I have to write my own routine/loop and keep calling substring or
string-match?

		Thanks,
