Des copies
ch caractère large dans chacun des premier count caractères larges de l'objet pointé par dest. Si l'objet n'est pas trivialement-copiable (par exemple, un scalaire, un tableau ou une structure C-compatible), le comportement est indéfini. Si les points dest+size+1 dehors de l'objet, le comportement est indéfini .Original:
Copies wide character
ch into each of the first count wide characters of the object pointed to by dest. If the object is not trivially-copyable (e.g., scalar, array, or a C-compatible struct), the behavior is undefined. If dest+size+1 points outside the object, the behavior is undefined.The text has been machine-translated via Google Translate.
