Clock Edge Interrupt Function (?)

Hello Labwindows community, 

Currently using Labwindows CVI 2012. 

I wanted to see if there was a function, in particular with the NI-DAQmx library (but not limited to), that allows for the detecting of the falling or rising edges of a pulse that occurs in microseconds. Is there an interrupt function or something similar that I can use to detect this and if the event occurs, to call a callback function?

Thanks,

Vincent
