Accessing a map using its reference

Question

I try to loop through a map, that I pass as a pointer to a function, but I can\'t find a way to access the elements. This is the code:

func refreshSession(sessio         


        

Answer 1

You are not taking into account the precedence of *.

*session[sid] really means *(session[sid]), that is, first indexing the pointer to map (hence the error), then dereferencing it.

You should use (*session)[sid].timestamp to first dereference the pointer to the map and then access it using the key.
