HWPutBytes
This function is called by a driver to write bytes to hardware.
ULONG HWPutBytes(
PVOID pContext,
PUCHAR pSrc,
ULONG NumberOfBytes,
PULONG pBytesSent );
Parameters
- pContext
Pointer to a context structure returned by the HWInit function that contains implementation-specific data describing the hardware device. - pSrc
Pointer to bytes to be sent. - NumberOfBytes
Specifies the number of bytes to be sent. - pBytesSent
Pointer to the actual number of bytes written.
Return Values
This function returns 0 or the minimum number of milliseconds before the MDD layer should call again. This is used if the device does not support interrupt-based indications of changes in the status of hardware flow-control lines. The MDD layer calls again to see if the flow-control condition has been removed.
Remarks
This function supports the implementation of the PDDs of serial port drivers.
