wctomb_s 函数将其 wchar 参数转换为相应的多字节字符并将结果存储在 mbchar。 在所有程序可以从任何函数点。 如果wctomb_s 转换宽字符转换为字节字符,它在宽字符放置 (比 MB_CUR_MAX不高) 的字节数为整数指向由 pRetValue。 如果 wchar 是宽字符 null 字符 (L' \ 0 "), wctomb_s 用 1. 加载 pRetVal...
towctombupdates the internal global conversion state (a static object of typembstate_t, known only to this function). If the multibyte encoding uses shift states, this function is not reentrant. In any case, multiple threads should not callwctombwithout synchronization:wcrtomborwctomb_smay be ...
