When I wrote the diskio code, I wanted to make file access a little
simpler.  If you look at the code that reads from FBFILE files, I
never use anything like feof().  The functions that read from the
buffers (like fbgetline and fbgetstring) check for an end of file
indication internally by testing for *fbfl-ptr.  Note that diskio
assumes you're always reading from a null-teminated text file.

If you've writtin a new fbget* function, I'd recommend following the
form of fbgetline and return a zero when !*fbfl->ptr.

If you're just using the existing functions to read a new file, you
can test for end of file as you read from it, as load_char does:

while(fbgetline(fl, line)) {

If you really want to check for EOF manually, you can use this:

int fbeof(FBFILE *fbfl)
    return -1;
    return 0;

The above will return a non-zero when you've reached the end of file.
