VC_Out

VOID
VC_Out(
    PDEVICE_INFO pDevInfo,
    BYTE bOffset,
    BYTE  bData
    );

The VC_Out function writes one byte into a device’s mapped I/O port address space.

Parameters

pDevInfo

Pointer to the DEVICE_INFO structure returned by VC_Init.

bOffset

Offset from the mapped I/O port’s base address.

bData

Data byte to be written.

Return Value

None.

Comments

A kernel-mode video capture driver specifies the base address of a device’s I/O port address space when calling VC_GetResources. The bOffset parameter to VC_Out specifies an offset from that base address.
