Si
s n'est pas un pointeur NULL, inspecte les octets plupart n de la chaîne de caractères multi-octets, en commençant par l'octet pointé par s pour déterminer le nombre d'octets nécessaires pour compléter le caractère multi-octets suivante (y compris les séquences de décalage). Si la fonction détermine que le caractère multi-octets prochaine s est complet et valide, il se convertit au correspondant caractères 16 bits et le stocke dans *pc16 (si pc16 n'est pas nulle) .Original:
If
s is not a null pointer, inspects at most n bytes of the multibyte character string, beginning with the byte pointed to by s to determine the number of bytes necessary to complete the next multibyte character (including any shift sequences). If the function determines that the next multibyte character in s is complete and valid, converts it to the corresponding 16-bit character and stores it in *pc16 (if pc16 is not null).The text has been machine-translated via Google Translate.

Si le caractère multi-octets dans
*s correspond à une séquence multi-char16_t (par exemple une paire de substitution UTF-16), puis après le premier appel à cette fonction, *ps est mis à jour de façon à ce que le prochain appel à mbrtoc16 écrira l' char16_t supplémentaires, sans tenir compte *s .Original:
If the multibyte character in
*s corresponds to a multi-char16_t sequence (e.g. a surrogate pair in UTF-16), then after the first call to this function, *ps is updated in such a way that the next call to mbrtoc16 will write out the additional char16_t, without considering *s.The text has been machine-translated via Google Translate.

Si
s est un pointeur nul, les valeurs de n et pc16 sont ignorés et l'appel est équivalent à std::mbrtoc16(NULL, "", 1, ps) .Original:
If
s is a null pointer, the values of n and pc16 are ignored and the call is equivalent to std::mbrtoc16(NULL, "", 1, ps).The text has been machine-translated via Google Translate.

Si le caractère large produite est le caractère nul, le *ps état de conversion représente l'état initial .
Original:
If the wide character produced is the null character, the conversion state *ps represents the initial shift state.

Si le __STDC_UTF_16__ macro est définie, l'encodage 16-bits utilisé par cette fonction est UTF-16, sinon il est défini par l'implémentation .
Original:
If the macro __STDC_UTF_16__ is defined, the 16-bit encoding used by this function is UTF-16, otherwise it is implementation-defined.
