Typedef Documentation

typedef void(* usb_callback_func)(void *cookie, status_t status, void *data, size_t actualLength)

Callback function for asynchronous transfers.

Parameters:

cookie	The cookie you supplied when you queued the transfer.
status	The status of the transfer. This is one of the following: B_OK The transfer succeeded. B_CANCELED The transfer was cancelled by the user via a usb_module_info::cancel_queued_transfers() call. B_DEV_MULTIPLE_ERRORS More than one of the errors below occurred. Unfortunately, the stack cannot give you more information. B_DEV_STALLED The endpoint is stalled. You can use usb_module_info::clear_feature() method with the associated pipe and the USB_FEATURE_ENDPOINT_HALT arguments. B_DEV_DATA_OVERRUN Incoming transfer: more data flowing in than the size of the buffer. B_DEV_DATA_UNDERRUN Outgoing transfer: more data is flowing out than the endpoint accepts. B_DEV_CRC_ERROR The internal data consistency checks of the USB protocol failed. It is best to retry. If you keep on getting this error there might be something wrong with the device. B_DEV_UNEXPECTED_PID There was an internal error. You should retry your transfer. B_DEV_FIFO_OVERRUN internal error. You should retry your transfer. B_DEV_FIFO_UNDERRUN There was an internal error. You should retry your transfer.
data	The provided buffer.
actualLength	The amount of bytes read or written during the transfer.
