程序运行调试日志的简单方法
程序运行调试日志的简单方法
1. 添加下面的宏
// 在调试状态下, 才会产生日志
#ifdef _DEBUG
#define WRITE_LOG(strLog) WriteLog(strLog, __FILE__, __LINE__, __FUNCTION__)
#define WRITE_DATA(strData, nDataLen) WriteData(strData, nDataLen)
#else
#define WRITE_LOG(strLog)
#define WRITE_DATA(strData, nDataLen)
#endif
#include <stdio.h>
void WriteLog(const char* strLog, char *pFile, int nLine, char *strFunction)
{
try
{
if(0 == strLog)
{
return;
}
if(0 == strlen(strLog))
{
return;
}
// 日志时间
SYSTEMTIME systime;
memset(&systime,0,sizeof(systime));
GetLocalTime(&systime);
FILE *pFile;
pFile=fopen("Log.Log","a+");
if(pFile!=NULL)
{
fprintf(pFile,"/n/n【%04d-%02d-%02d %02d:%02d:%02d.%03d】【%s(%d)-%s】/n【LOG】%s/n",systime.wYear,systime.wMonth,
systime.wDay,systime.wHour,systime.wMinute,systime.wSecond,systime.wMilliseconds,
sFile,nLine,sFunction,strLog);
fclose(pFile);
}
}catch(...){}
}
void WriteData(const unsigned char* strLog,int nLength)
{
try
{
if (0 == strLog )
{
return ;
}
if (0 == nLength )
{
return ;
}
int nLineByte = 0; //行字节数
FILE *pFile;
pFile=fopen("Data.Log","a+");
if(pFile!=NULL)
{
fprintf(pFile,"/n/n【DATA】/n");
for (int i=0; i<nLength; i++)
{
if (nLineByte == 32)
{
fprintf(pFile,"/n");
nLineByte = 0;
}
fprintf(pFile,"%02x ",strLog[i]);
nLineByte++;
}
fprintf(pFile,"/n");
fclose(pFile);
}
}catch(...){}
#endif
}
// 使用
WRITE_LOG("received the invite message from server");
WRITE_DATA((unsigned char*)pdata, nDataLen);
