Windows Driver Kit DDI reference (nf-miniport-write_port_buffer_ushort)

WRITE_PORT_BUFFER_USHORT function (miniport.h)

Description

The WRITE_PORT_BUFFER_USHORT routine writes a number of USHORT values from a buffer to the specified port address.

Parameters

Port [in]

Pointer to the port, which must be a mapped memory range in I/O space.

Buffer [in]

Pointer to a buffer from which an array of USHORT values is to be written.

Count [in]

Specifies the number of USHORT values to be written to the port.

Remarks

The size of the buffer must be large enough to contain at least the specified number of USHORT values.

Callers of WRITE_PORT_BUFFER_USHORT can be running at any IRQL, assuming the Buffer is resident and the Port is resident, mapped device memory.
