This parameter is passed to the InterruptInitialize function in the Hardware Emulation Layer ( HAL ). It originally was intended for the interrupt service routine to handle receive characters in a fast path, but currently is unused.

Return Values

Remarks

This function supports the implementation of the PDDs of serial port drivers. This function is defined in the header file SerHW.h, and is available in Windows CE version 1.0 and later.
