Question

I need to shorten wchar_t array. Example:

wchar_t* email = L"[e-mail]";
/ * Somehow leave in email just "name" * /

My idea to do that

wchar_t Domain = L"@domain.com";
if(!(pos = wcsstr(email, Domain)))
    return 0;

wcsncpy (pos,L"",1);

wcsstr returns address to “@domain.com”(0x000001 – email begins, 0x000005 @domain.com begins ) but there wont be any memory leaks or garbage?

Answer 1

No, that won’t create any memory leaks because you aren’t allocating any memory, or modifying your original email pointer.

An easier and more efficient syntax, though, would be *pos = '\0';
