The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

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