interrupt requests

[kian chong]

i have a 6034E daq card and i wish to make use of its counter to improve the accuracy of the gps signals which provide a 1PPS signal. By using a timebase of 100KHz, i will know that 1 second is reached when 100 counts. However, to keep accurate timing, i need to reset the counter whenever the 1PPS signal (input) goes high. How do i write the source code using visual C++ to generate an interrupt to reset the counter whenever the 1PPS signal goes high. The 1PPS signal will go high for 10ms for every 1 sec and it is highly accurate. Please advise.Thanks!
