get length of `wchar_t*` in c++

Please, how can I find out the length of a variable of type wchar_t* in c++?

code example below:

wchar_t* dimObjPrefix = L"retro_";

I would like to find out how many characters dimObjPrefix contains

Solution

  • If you want to know the size of a wchar_t string (wchar_t *), you want to use wcslen(3):

    size_t wcslen (const wchar_t *ws);
