自定义TRACE函数,用于向Output Window、控制台和文件输出Log

自己写了一个Multi-Byte和UNICODE两个版本的TRACE函数。

#include <windows.h>
#include <stdio.h>
#define BUFSIZE_MAX 1024

#ifdef _DEBUG
#ifdef UNICODE
static void MYTRACE(wchar_t *fmt, ...)
{
	// 取得时间戳 [年-月-日 时:分:秒]
	SYSTEMTIME time;
	GetLocalTime(&time);
	wchar_t timeBuf[21] = {0};
	swprintf_s(timeBuf, L"[%d-%d-%d %d:%d:%d]", time.wYear, time.wMonth, time.wDay, 
		time.wHour, time.wMinute, time.wSecond);

	va_list args;
	wchar_t buf[BUFSIZE_MAX] = {'\0'};
	va_start(args, fmt);
	_vsnwprintf_s(buf, BUFSIZE_MAX, fmt, args);
	// output to debug window.
	OutputDebugString(timeBuf);
	OutputDebugString(buf);

	// output to console.
	printf("%s%s", timeBuf, buf);

	// output to file.
	FILE *fp = NULL;
	_wfopen_s(&fp, L"debug.log", L"a+,ccs=UTF-8");
	fputws(timeBuf, fp);
	fputws(buf, fp);
	fclose(fp);
}
#else // UNICODE
static __inline void MYTRACE(char *fmt, ...)
{
	// 取得时间戳 [年-月-日 时:分:秒]
	SYSTEMTIME time;
	GetLocalTime(&time);
	char timeBuf[21] = {'\0'};
	sprintf(timeBuf, "[%d-%d-%d %d:%d:%d]", time.wYear, time.wMonth, time.wDay, 
		time.wHour, time.wMinute, time.wSecond);

	va_list args;
	char buf[BUFSIZE_MAX] = {'\0'};
	va_start(args, fmt);
	vsprintf(buf, fmt, args);
	// output to debug window.
	OutputDebugString(timeBuf);
	OutputDebugString(buf);

	// output to console.
	printf("%s%s", timeBuf, buf);

	// output to file.
	FILE *fp = fopen("debug.log","a+");
	fwrite(timeBuf,strlen(timeBuf),1,fp);
	fwrite(buf,strlen(buf),1,fp);
	fclose(fp);
}
#endif // UNICODE
#else // _DEBUG
static inline MYTRACE(char* fmtStr, ...) {}
#endif // _DEBUG
