Always remember where your file pointer was before you read the last line. So:

lnLastPos=Fseek(gfh, 0,1) zero bytes offset, from current position
yourString=Fgets(gfh)

[ crunch & munch the data ]

=fseek(gfh, lnLastPos,0) go back to where you were (exact position offset, from start of file)
=fwrite(gfh, YourNewString)

Your new string should be padded with some blanks to the length of the string you got first, and surely not longer than it.
