WinUsb_AbortPipe function (winusb.h)
The WinUsb_AbortPipe function aborts all of the pending transfers for a pipe. This is a synchronous operation.
Syntax
BOOL WinUsb_AbortPipe(
[in] WINUSB_INTERFACE_HANDLE InterfaceHandle,
[in] UCHAR PipeID
);
Parameters
[in] InterfaceHandle
An opaque handle to an interface that contains the endpoint with which the pipe is associated.
To abort transfers on the pipe associated with the endpoint in the first interface, use the handle returned by WinUsb_Initialize. For all other interfaces, use the handle to the target interface, retrieved by WinUsb_GetAssociatedInterface.
[in] PipeID
The identifier (ID) of the control pipe. The PipeID parameter is an 8-bit value that consists of a 7-bit address and a direction bit. This parameter corresponds to the bEndpointAddress field in the endpoint descriptor.
Return value
WinUsb_AbortPipe returns TRUE if the operation succeeds. Otherwise, this routine returns FALSE, and the caller can retrieve the logged error by calling GetLastError.
GetLastError can return the following error code.
