Thanks for the responses. Greg, your implementation looks useful but it's a little different than what I was thinking (my apologies, I wasn't very clear).
In the implementation you posted, the timeout parameter is used to limit the amount of time spent waiting to read an individual character - I was hoping to use the timeout as an initial value for a timer that should start running when hReadUntilStr is evaluated and the function should finish evaluating when either the timer has run out or when the string match has been found. Martin, thanks for the link. Cheers, Matt On 2/3/07, Greg Fitzgerald <[EMAIL PROTECTED]> wrote:

It throws an IO exception if hWaitForChar times out, and makes use of lazy evaluation to schedule all the IO upfront so that grabbing the string prefix can be done in pure code. Thanks, Greg
