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");

case WM_COMMAND:
wmId    = LOWORD(wParam); 
wmEvent = HIWORD(wParam); 
// Parse the menu selections:
switch (wmId)
{
    case IDS_BTN1:
        OutputDebugString("1");
        break;
    case IDS_CLEAR:
        SetWindowText(GetDlgItem(hWnd,IDS_EDIT),(LPCTSTR)"");
        break;
    case IDM_ABOUT:
        DialogBox(hInst, (LPCTSTR)IDD_ABOUTBOX, hWnd, (DLGPROC)About);
        break;
    case IDM_EXIT:
        DestroyWindow(hWnd);
        break;
    default:
        return DefWindowProc(hWnd, message, wParam, lParam);
}
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");

#include <stdio.h>
#include <stdarg.h>
#include <stdlib.h>
#include <windows.h>

void __cdecl odprintf(const char *format, ...)
{
    char buf[4096], *p = buf;
    va_list args;
    
    va_start(args, format);
    p += _vsnprintf(p, sizeof buf - 1, format, args);
    va_end(args);
    
    while ( p > buf && isspace(p[-1]) )
    {
        *--p = '';
        *p++ = '
';
        *p++ = '
';*p = '';
    }
    OutputDebugString(buf);
} 

使用方法:

odprintf("Cannot open file %s [err=%ld]", "test.c", 110201);

编译运行之后使用方法一查看
