その32ビットの文字表現(一般的には、UTF-32)にナローマルチバイト文字に変換し.
Original:
Converts a narrow multibyte character to its 32-bit character representation (typically, UTF-32).

sがNULLポインタでない場合は、次のマルチバイト文字(任意のシフトシーケンスを含む)を完了するのに必要なバイト数を決定するためにnが指すバイトから始めて、マルチバイト文字列の中で最もsバイトを検査します。関数はsで次のマルチバイト文字が完全かつ有効であると判断した場合、対応する32ビットの文字に変換して*pc32に格納(pc32nullでない場合).
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 32-bit character and stores it in *pc32 (if pc32 is not null).

*sにマルチバイト文字がマルチchar32_tシーケンス(UTF-32では可能ではない)に対応している場合、この関数の最初の呼び出しの後に、*psmbrtoc32隣にコールが追加char32_tを書き出すような方法で更新されます、*sを考慮せずに.
Original:
If the multibyte character in *s corresponds to a multi-char32_t sequence (not possible with UTF-32), then after the first call to this function, *ps is updated in such a way that the next calls to mbrtoc32 will write out the additional char32_t, without considering *s.

sがNULLポインターである場合、値npc32無視され、コールがstd::mbrtoc32(NULL, "", 1, ps)に相当するものであり.
Original:
If s is a null pointer, the values of n and pc32 are ignored and the call is equivalent to std::mbrtoc32(NULL, "", 1, ps).

生産ワイド文字がヌル文字である場合、変換状態*psは初期シフト状態を表します.
Original:
If the wide character produced is the null character, the conversion state *ps represents the initial shift state.

Original:
If the macro __STDC_UTF_32__ is defined, the 32-bit encoding used by this function is UTF-32, otherwise it is implementation-defined.
