libusb_transfer_cb_fn - syntax, references, description

Asynchronous transfer callback function type. When submitting asynchronous transfers, you pass a pointer to a callback function of this type via the libusb_transfer ::callback "callback" member of the libusb_transfer structure. libusb will call this function later, when the transfer has completed or failed. See libusb_asyncio for more information.
