Windows Unicode相关

====头文件前后顺序影响TCHAR定义===============================
windows.h winnt.h
tchar.h
======定义_UNICODE宏常量控制==================
//字符
typedef char TCHAR;
typedef wchar_t TCHAR;

字符串
typedef __T(x) L##x
typedef __T(x) x

//C库函数
#define _tcslen strlen
#define _tcslen wcslen
#define _tmain main
#define _tmain wmain
#define _tWinMain WinMain
#define _tWinMain wWinMain

=====定义UNICODE常量控制=========================
字符
typedef CHAR TCHAR
typedef WCHAR TCHAR
字符串
#define __TEXT(x) L##x
#define __TEXT(x) x

typedef LPSTR PTSTR, LPTSTR;
typedef LPWSTR PTSTR, LPTSTR;

//系统函数
#define MessageBox MessageBoxA
#define MessageBox MessageBoxW

=====在tchar.h中定义======================
TCHAR
__T(x)
#define _T(x) __T(x)
#define _TEXT(x) __T(x)

//C库函数
_tcslen
_tmain
_tWinMain

======在winnt.h中定义======================
//字符
TCHAR

typedef char CHAR;
typedef wchar_t WCHAR;

//字符串
__TEXT(x)
#define TEXT(x) __TEXT(x)

PTSTR, LPTSTR

补充：
mainCRTStartup()/wmainCRTStartup() 位于C运行库，它先执行，然后调用main()/wmain()；
//main入口
int _tmain(void);
int _tmain(int argc, TCHAR **argv);
int _tmain(int argc, TCHAR *argv[]);
当入口点是WinMain,执行程序开始于WinMainCRTStartup，同理wWainMain,其开始在wWinMainCRTStartup
//WinMain入口
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow);
int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow);

 

/SUBSYSTEM

link 指定/DLL 入口点DllMainCRTStartup 调用 DllMain  __stdcall调用方式

 

带dos调试窗口的win32程序
#pragma comment( linker, "/subsystem:console /entry:WinMainCRTStartup")

 

window API字符串函数
字符串长度
int WINAPI lstrlenA(LPCSTR lpString);
int WINAPI lstrlenW(LPCWSTR lpString);
拼接字符串
LPWSTR WINAPI lstrcatW(LPWSTR lpString1, LPCWSTR lpString2);
字符串大小写转换
LPWSTR WINAPI CharLowerW(LPWSTR lpsz);
LPWSTR WINAPI CharUpperW(LPWSTR lpsz);
