The VPICD_Remove_Handler function removes a bimodal interrupt handler for the IRQ specified by the BIS_IRQ_Number field in the Bimodal_Int_Struc structure.
bis
Points to a Bimodal_Int_Struc structure containing information about the interrupt handler to remove.
lpfnVPICD
Specifies the entry-point address of the API handler for the virtual PIC device.
The carry flag is clear if the function is successful, and set if an error occurs. The function returns an error if the IRQ has not been virtualized, or the IRQ number is not valid.
This function unvirtualizes the specified IRQ, and frees the supervisor-mode selectors for the interrupt handler's code, data, and additional segments (if any).
