How is the result struct of localtime allocated in C?

Question

I was playing with the time.h file in C that helps us with time/day functions.

I came across:

struct tm * _Cdecl localtime(const time_t          


        

Answer 1

Actually localtime usually returns the address of a static object. I suspect it looks like this:

struct tm *
localtime(const time_t *timer)
{
    static struct tm tm;

    /* Magic. */

    return &tm;
}
