Fields
- fPosition - Placement flag.
- The DosMonReg function call parameter that is used by an application to indicate:
- Where its monitor buffers are to be placed within a monitor chain relative to monitors already registered on the monitor chain
- What special processing requirements need to be supported by the monitor dispatcher.
- Refer to the IOCtl function 40h for valid parameter values.
- index - Index.
- Used by an application to indicate on which monitor chain its monitor buffers are being registered. The accepted values for this parameter vary for each device driver. See information on the physical mouse device driver, the physical keyboard device driver and the physical parallel port device driver in the OS/2 Input/Output Device Driver Reference to determine the valid parameter value for each device driver.
- Refer to the IOCtl function 40h for valid parameter values.
- pbInBuf - Address of the Input Buffer.
- Specifies the address of a monitor input buffer allocated by an application, initialized by the monitor dispatcher, and used by the DosMonRead function.
- offOutBuf - Offset of the Output Buffer.
- Specifies the offset of a monitor output buffer allocated by an application in the same data segment as the input buffer, initialized by the monitor dispatcher, and used by the DosMonWrite function.
