/* ffilecopy -- very fast buffered file copy
*
* Usage: i = ffilecopy (here,there)
* int i;
* FILE *here, *there;
*
* Ffilecopy is a routine to copy the rest of a buffered
* input file to a buffered output file. Here and there are open
* buffered files for reading and writing (respectively).
* Ffilecopy returns 0 if everything was OK; EOF if
* there was any error. Normally, the input file will be left in
* EOF state (feof(here) will return TRUE), and the output file will be
* flushed (i.e. all data on the file rather in the core buffer).
* It is not necessary to flush the output file before ffilecopy.
