IWDFUsbTargetPipe::IsInEndPoint method

The IsInEndPoint method determines whether a USB pipe (endpoint) is an IN pipe.

Syntax


BOOL  IsInEndPoint();

Parameters

This method has no parameters.

Return value

IsInEndPoint returns a BOOL value that indicates whether the USB pipe is an IN pipe. TRUE indicates the pipe is an IN pipe. FALSE indicates the pipe is not an IN pipe.

Remarks

If the USB pipe is an IN pipe, a UMDF driver can call the IWDFIoTarget::FormatRequestForRead method to format a read request. The framework can then send the request to the USB pipe.

Note The meaning of IN and OUT is opposite in WDF and USB.

Examples

For a code example of how to use the IsInEndPoint method, see IWDFUsbInterface::GetNumEndPoints.
