HWPutBytes

This function is called by a driver to write bytes to hardware.

Syntax

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. This function is defined in the header file SerHW.h, and is available in Windows CE version 1.0 and later.
