/* 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.
