IWDFUsbTargetPipe::IsInEndPoint method (wudfusb.h)
[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
The IsInEndPoint method determines whether a USB pipe (endpoint) is an IN pipe.
Syntax
BOOL IsInEndPoint();
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.
Examples
For a code example of how to use the IsInEndPoint method, see IWDFUsbInterface::GetNumEndPoints.
