It was 23:18:11 16 Nov 98 in C_ECHO, when the peace was suddenly disturbed
by Kurt screaming TC++ Delay() function... at Dominique Curtis. This then
followed:

 KK>    Since you are subject to system delays, the code delay may
 KK>    append to a system delay and produce an extended delay, which
 KK>    is not what you intended. Your timing routine in such cases
 KK>    should be based on system time, not on a time-based delay.
 KK>    Using the standard clock() function, you can set a point at
 KK>    which your routine will execute. If the system delays push
 KK>    your time past that point, then it will execute immediately,
 KK>    and if not, then you will have your desired delay.

According to the Linux manpage:

DESCRIPTION
       The clock() function returns an approximation of processor
       time used by the program.

So it will be effected by multi-tasker delays. Also, under a multi-tasker
like Linux, you will want to go into a sleep state. The POSIX function
sleep() does this. You could use time(), but this would be inaccurate.
