..\display.h(72): warning: #231-D: declaration is not visible outside of function

..\display.h(72): warning: #231-D: declaration is not visible outside of function

I got message when I included a header file containing this line:

void DISPLAY_string_date_time(const struct tm * tim, DISPLAY_MSG * p_message);

I found the problem - I hadn't included <time.h> in the two cases that caused the warning.

After a lot of searching for what this warning means, I can't find any explanation.

Can anyone translate what the compiler is saying?

    You are right.

    The compiler makes a difference between:

    int function(struct tm* t);


    and

    struct tm;
int function(struct tm* t);

    I haven't thought about this case before. I always have the second alternative, if I need to make use of a struct or class pointer without letting the header file see the full definition.
