READ_PORT_BUFFER_ULONG(
IN PULONG Port,
IN PULONG Buffer,
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.
