win32程序调试OutputDebugString 类似printf格式化输出

有没有win32编程因为打印变量调试程序而头疼呢.方法二的函数完全类似printf.非常完美.
方法一:
不带参数输出如printf("hello world");

OutputDebugString("debug");

 1 case WM_COMMAND:
 2 wmId    = LOWORD(wParam); 
 3 wmEvent = HIWORD(wParam); 
 4 // Parse the menu selections:
 5 switch (wmId)
 6 {
 7     case IDS_BTN1:
 8         OutputDebugString("1");
 9         break;
10     case IDS_CLEAR:
11         SetWindowText(GetDlgItem(hWnd,IDS_EDIT),(LPCTSTR)"");
12         break;
13     case IDM_ABOUT:
14         DialogBox(hInst, (LPCTSTR)IDD_ABOUTBOX, hWnd, (DLGPROC)About);
15         break;
16     case IDM_EXIT:
17         DestroyWindow(hWnd);
18         break;
19     default:
20         return DefWindowProc(hWnd, message, wParam, lParam);
21 }
22 break;

使用工具debug view查看:

方法二:

带参数输出入如 printf("hello %s welcome this %d ", "world", "501");

 1 #include <stdio.h>
 2 #include <stdarg.h>
 3 #include <stdlib.h>
 4 #include <windows.h>
 5 
 6 void __cdecl odprintf(const char *format, ...)
 7 {
 8     char buf[4096], *p = buf;
 9     va_list args;
10     
11     va_start(args, format);
12     p += _vsnprintf(p, sizeof buf - 1, format, args);
13     va_end(args);
14     
15     while ( p > buf && isspace(p[-1]) )
16     {
17         *--p = '
