Documentation des définition de type

typedef __object_type mbstate_t

Type objet, autre qu'un tableau, contenant l'information d'état nécessaire aux conversions entre caractères multibytes et caractères larges

typedef __unsigned size_t

Ce type entier non signé est capable de contenir la taille des objets.

Voir stddef.h pour plus d'informations.

typedef __integral wchar_t

Ce type entier est capable de représenter tous les codes pour le charset le plus étendu parmi les charsets des locales supportées.

Voir stddef.h pour plus d'informations.

typedef __integral wint_t

Voir <wctype.h>
