All this time I've been using the return value of snprintf as the number of characters actually written, when it's in fact the number of characters that would be written if the max size passed in were large enough.
In fact: "If the resulting string would be longer than n-1 characters, the remaining characters are discarded and not stored, but counted for the value returned by the function."
@gfxstrand Good to know, will definitely be checking that.
Of course to be sure I should check the behaviour on Windows 11, Windows 10... Windows 8.1, Windows 8... Windows XP, 2000... Windows Me, no just kidding on that last one.
