[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 IsOutEndPoint method determines whether a USB pipe (endpoint) is an OUT pipe.
This function has no parameters.
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.
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.
For a code example of how to use the IsOutEndPoint method, see IWDFUsbInterface::GetNumEndPoints.
|End of support||Unavailable in UMDF 2.0 and later.|
|Minimum UMDF version||1.5|
