IWDFUsbTargetPipe::IsOutEndPoint method

The IsOutEndPoint method determines whether a USB pipe (endpoint) is an OUT pipe.

Syntax


BOOL  IsOutEndPoint();

Parameters

This method has no parameters.

Return value

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

Remarks

If the USB pipe is an OUT pipe, a UMDF driver can call the IWDFIoTarget::FormatRequestForWrite method to format a write 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 IsOutEndPoint method, see IWDFUsbInterface::GetNumEndPoints.
