To add, notably this: _snprintf, _snprintf_l, _snwprintf, _snwprintf_l -> https://msdn.microsoft.com/en-us/library/2ts7cx93.aspx https://msdn.microsoft.com/en-us/library/2ts7cx93.aspx "If len > count, count characters are stored in buffer, no null-terminator is appended, and a negative value is returned." Uh, what? I guess that's why it is _snprintf and not snprintf, huh? They do provide secure [1] versions too, but you need to be careful which one you pick. Those secure versions terminate execution in some cases if buffer length is exceeded.
