LPT square wave

Hi,

I'm trying to write a program in C++ to communicate with an AVR
microcontroller's SPI via the LPT port.

I have to generate a clock (SCK) signal on one of the pins of the LPT.
I am using the WinIO library. I'd like to have way to create a square
wave of a given frequency (within some limit of course).

My question is: what is the best way to generate such signal and what
is the maximum frequency one can obtain? Excluding of course such code:
Code:

for (;;) {
pin = 0; pin = 1;
}

.
