NTSTATUS cbmiec_i_raw_read (  IN PDEVICE_EXTENSION  Pdx, OUT UCHAR *  Buffer, ULONG  Count, OUT ULONG *  Received )

Read some bytes from the IEC bus. Parameters: Pdx  Pointer to the device extension. Buffer  Pointer to a buffer where the read bytes are written to. Count  Maximum number of characters to read from the bus. Received  Pointer to the variable which will hold the read bytes. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values. Definition at line 46 of file i_rawread.c.
