宽字符函数普通C函数描述wcscoll strcoll 比较字符串日期和时间转换宽字符函数描述strftime 根据指定的字符串格式和locale设置格式化日期和时间wcsftime 根据指定的字符串格式和locale设置格式化日期和时间 并返回宽字符串strptime 根据指定格式把字符串转换为时间值 是strftime的反过程打印和扫描字符串宽字符函数描述fprintf/fwprintf 使用vararg参量的格式化输出fscanf/fwscanf 格式化读入printf 使用vararg参量的格式化输出到标准输出scanf 从标准输入的格式化读入sprintf/swprintf 根据vararg参量表格式化成字符串sscanf 以字符串作格式化读入vfprintf/vfwprintf 使用stdarg参量表格式化输出到文件vprintf 使用stdarg参量表格式化输出到标准输出vsprintf/vswprintf 格式化stdarg参量表并写到字符串数字转换宽字符函数 普通C函数描述wcstod strtod 把宽字符的初始部分转换为双精度浮点数wcstol strtol 把宽字符的初始部分转换为长整数wcstoul strtoul 把宽字符的初始部分转换为无符号长整数多字节字符和宽字符转换及操作宽字符函数描述mblen 根据locale的设置确定字符的字节数mbstowcs 把多字节字符串转换为宽字符串mbtowc/btowc 把多字节字符转换为宽字符wcstombs 把宽字符串转换为多字节字符串wctomb/wctob 把宽字符转换为多字节字符输入和输出宽字符函数 普通C函数描述fgetwc fgetc 从流中读入一个字符并转换为宽字符fgetws fgets 从流中读入一个字符串并转换为宽字符串fputwc fputc 把宽字符转换为多字节字符并且输出到标准输出fputws fputs 把宽字符串转换为多字节字符并且输出到标准输出串getwc getc 从标准输入中读取字符 并且转换为宽字符getwchar getchar 从标准输入中读取字符 并且转换为宽字符None gets 使用fgetwsputwc putc 把宽字符转换成多字节字符并且写到标准输出putwchar putchar 把宽字符转换成多字节字符并且写到标准输出None puts 使用fputwsungetwc ungetc 把一个宽字符放回到输入流中字符串操作宽字符函数 普通C函数描述wcscat strcat 把一个字符串接到另一个字符串的尾部wcsncat strncat 类似于wcscat 而且指定粘接字符串的粘接长度.wcschr strchr 查找子字符串的第一个位置wcsrchr strrchr 从尾部开始查找子字符串出现的第一个位置wcspbrk strpbrk 从一字符字符串中查找另一字符串中任何一个字符第一次出现的位置wcswcs/wcsstr strchr 在一字符串中查找另一字符串第一次出现的位置wcscspn strcspn 返回不包含第二个字符串的的初始数目wcsspn strspn 返回包含第二个字符串的初始数目wcscpy strcpy 拷贝字符串wcsncpy strncpy 类似于wcscpy 同时指定拷贝的数目wcscmp strcmp 比较两个宽字符串wcsncmp strncmp 类似于wcscmp 还要指定比较字符字符串的数目wcslen strlen 获得宽字符串的数目wcstok strtok 根据标示符把宽字符串分解成一系列字符串wcswidth None 获得宽字符串的宽度wcwidth None 获得宽字符的宽度另外还有对应于memory操作的 wmemcpy wmemchr wmemcmp wmemmove wmemsetTCHAR 函数对照表Generic-Text Routine Mappings宽字符和普通字符串处理函数_c# 宽字符处理函数-CSDN博客Generic-text routine name SBCS (_UNICODE MBCS not defined) _MBCS
