class CallbackRequest

Defined at line 391 of file ../../src/devices/usb/lib/usb/include/usb/request-cpp.h

A special Request type which can contain a callback lambda to be executed

upon completion of a USB request. The callback_size parameter represents the

size of the callback, and must be at least sizeof(std::max_align_t) bytes.

Public Methods

void CallbackRequest<callback_size> (usb_request_t * request, size_t parent_request_size)

void take ()

It is NOT safe to call take() on a CallbackRequest.

In order to ensure that each CallbackRequest is only

ever invoked once, we make it an error to call take().
