Hello,
in the course ESP32 build webserver on page 248 in the listing I don’t understand the following notation:
[] (AsyncWebServerRequest * request) {….
* request is a pointer of type AsyncWebServerRequest or what else? does [ ] mean that an array is returned?
Thanks
Best regards
Ferdinnado

Sorry I forgot the function pointers, now I think it is: * request is a AsyncWebServerRequest object pointer to allow use the send method and returns an array … can it be?

I found the solution: C++ Lambda functions [capture] (argument list) {body function}
Sorry but I didn’t know about this C ++ feature.
