对于在某些情况下，在非console程序中需要控制台来打印日志方便的调试程序。可以用下面这个类。写的粗糙，
class CConsoleLog
{
public:
CConsoleLog(void);
~CConsoleLog(void);
void Log(char *format, ...);
};
#include <Windows.h>
#include <stdio.h>
#include <stdarg.h>
CConsoleLog::CConsoleLog(void)
{
BOOL ret = AllocConsole();
if(!ret)
{
throw "allocconsole failed";
}
freopen("CON", "w", stdout);
}
CConsoleLog::~CConsoleLog(void)
{
BOOL ret = FreeConsole();
if(!ret)
{
throw "free console failed";
}
}
void CConsoleLog::Log(char *format, ...)
{
va_list ap;
char buf[255] = {0};
va_start(ap, format);
vsprintf(buf, format, ap);
va_end(ap);
fprintf(stdout, buf);
return;
}
记下，方便以后查找
