This function aborts an active transfer.

Syntax

BOOL AbortTransfer(
  LPCUSB_FUNCS pUsbFuncs,
  USB_TRANSFER hTransfer,
  DWORD dwFlags 
);

Parameters

  • pUsbFuncs
    [in] Pointer to a USB_FUNCS structure.
  • hTransfer
    [in] USB transfer handle.
  • dwFlags
    [in] Value of USB_NO_WAIT or zero (0).

Return Value

TRUE indicates success. FALSE indicates failure.

Remarks

This function halts a pending transfer. It blocks until the transfer is successfully canceled unless you specify USB_NO_WAIT. If you specify USB_NO_WAIT, the transfer is flagged for cancellation and this function returns immediately. If a completion callback function was registered when the transfer was issued, the completion callback function executes.
