end of file not recognized

[2dye4]

The following is my program

FILE *floppy;
FILE *destination;
floppy=fopen("a:\picture.jpg","rb");
destination=fopen("c:\pictures\save.jpg","rb");
do
{
hold=fgetc(floppy);
fputc(hold,destination);
}while(!feof(floppy);


The goal is copy a picture file from a floppy to
the hard drive. Worked fine until in encountered
a corrupt file on the floppy and then there was
no ending to this loop. feof never returned a non-zero
value. It wrote a 1.3 Gig file to my hard drive before
I canceled the program.
I know I can count bytes and stop at an absurd number
but there should be a more elegant way
This was compiled to a win32 console app with borland 5.5
and was running on Winxp home
any ideas
Thanks

You have header information in image files to help in such matters, so use it. No need to continue reading bytes. If the header info looks corrupted, there's no need to continue reading.
