C++ 字符串操作函数集合（部分）

String Manipulation (CRT)

String manipulation routines operate onnull-terminated single-byte character and wide-character strings. Use thebuffer-manipulation routines, described in Buffer Manipulation, to work withcharacter arrays that do not end with a null

character.

 Generally, Windows CE supportswide-character versions of functions rather than other versions. This enablesWindows CE to support Unicode while keeping the library compact.
