WdfUsbTargetPipeIsOutEndpoint function (wdfusb.h)
[Applies to KMDF and UMDF]
The WdfUsbTargetPipeIsOutEndpoint method determines whether a specified USB pipe is connected to an output endpoint.
Syntax
BOOLEAN WdfUsbTargetPipeIsOutEndpoint(
[in] WDFUSBPIPE Pipe
);
Parameters
[in] Pipe
A handle to a framework pipe object that represents a bulk pipe or interrupt pipe and was obtained by calling WdfUsbInterfaceGetConfiguredPipe.
Return value
WdfUsbTargetPipeIsOutEndpoint returns TRUE if the pipe that the Pipe handle represents an output endpoint. The method returns FALSE if the endpoint is an input endpoint.
