Operations on files

rename
tmpnam tmpnam_s (C11)

定义于头文件 `<wchar.h>`
wchar_t * fgetws ( wchar_t * str, int count, FILE * stream ) ;		(自 C95 起) (直至 C99)
wchar_t * fgetws ( wchar_t * restrict str, int count, FILE * restrict stream ) ;		(自 C99 起)

从给定的文件流中读取最多 count - 1 个宽字符并存储到 str 中。生成的宽字符串始终以空字符结尾。解析在遇到文件结束或换行宽字符时停止，这种情况下 str 将包含该换行宽字符。

wscanf fwscanf swscanf wscanf_s fwscanf_s swscanf_s (C95) (C95) (C95) (C11) (C11) (C11)	从标准输入、文件流或缓冲区读取格式化宽字符输入 (函数)
fgetwc getwc (C95)	从文件流获取一个宽字符 (函数)
fputws (C95)	向文件流写入一个宽字符串 (函数)
getline getwline getdelim getwdelim (动态内存 TR)	从流读取数据到自动调整大小的缓冲区，直到遇到分隔符/行结束 (函数)
