Here is an answer to your second question:

#define HEAD *(int far *)MK_FP(0x40, 0x1a))
#define TAIL *(int far *)MK_FP(0x40, 0x1c))

	HEAD = TAIL;	// Flush keyboard buffer

This routine works by resetting the head pointer (offset) to the same
value as the tail pointer, which by definition, means the buffer is
empty.

Don't ask me....

>HOw can you flush the keyboard buffer?

In Turbo C, simply:

	while (kbhit())
		getch();	/* while character in buffer, read it and
					discard */

Well, it depends on what you mean by fast, I suppose (to program, or
to execute....)

If you're using Turbo C, you can look at the commands findfirst(),
findnext() (which let you get the files in the directory) and unlink()
(which deletes a file).

Please retain any and all materials that are NOT specifically source code
(i.e. requests for code, discussions of code, programming questions in
general) from this newsgroup. Many sites archive this group, and must go
through extra, unnecessary work to weed out all of the exterraneous postings.
In addition, this is simply not the place. There is an alt.sources.d for 
discussion, alt.sources.wanted for those looking for code, as well as
programming newsgroups that specifically deal with the questions recently
posed here in alt.sources.

I apologize for posting material not source related, but the "miscellaneous"
postings were numbering high.

Normally, this can't be done. A "lock" file is often used for this purpose 
(a lock file is another file whose existence signals some fact, but this
requires that all programs obey the convention of using that particular
lock file)

If your library has a "system()" function, try this:

	system( "del *.*" );
