        IN ULONG  Count
        );

READ_PORT_BUFFER_ULONG reads a number of ULONG values from the specified port address into a buffer.

Parameters

Port

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

Buffer

Points to a buffer into which an array of ULONG values is read.

Count

Specifies the number of ULONG values to be read into the buffer.

Comments

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

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