No.  FILE *fp is NOT a string!  It is a pointer returned by `fopen'.  So 
at least you should have said this:

mypc=read_one_line(&mypc, myLenWanted,myLineWanted,
		   fopen("data.txt", "r"));

I would also check the value returned from `fopen', since it could be a 
NUL pointer if the file didn't exist, for example.
