C typeid

WebIn a typical C++ program, you would use the typeid operator, like this: std::cout << typeid (myVar).name (); However, that requires a compiler feature called Runtime Type Information (RTTI). It's disabled in the Arduino IDE, presumably because it tends to increase the runtime memory requirements of the program. WebGet type name Returns a null-terminated character sequence that may identify the type. The particular representation pointed by the returned value is implementation-defined, and may or may not be different for different types. Parameters none Return Value A pointer to a c-string with the name for the object. Example 1 2 3 4 5 6 7 8 9 10 11 12 13 14
