call    [lpfnVPICD]
jc      error

Removes a bimodal interrupt handler for the IRQ specified by the BIS_IRQ_Number field in the Bimodal_Int_Struc structure.

• Clears the carry flag if successful; sets it if an error occurs. The function returns an error if the IRQ has not been virtualized, or the IRQ number is not valid.

bis

Address of a Bimodal_Int_Struc structure containing information about the interrupt handler to remove.

lpfnVPICD

Entry-point address of the API handler for the virtual PIC device.

This function unvirtualizes the specified IRQ, and frees the supervisor-mode selectors for the interrupt handler's code, data, and additional segments (if any).
