小编use*_*556的帖子

我编写了以下代码来将日志写入我的日志文件中。这段代码可以很好地记录消息，但现在我必须将其集成到多个文件中，我需要调用者的文件路径、调用者函数名称和行号。

请帮助我实现这一目标。

#include "Source.h"

bool CLogManager::fileOpenError = false;
std::string CLogManager::logFileName = "";
CLogManager* CLogManager::logManager = NULL;
FILE* CLogManager::file = NULL;

CLogManager :: CLogManager(){}
CLogManager :: ~CLogManager()
{
    if (file)
        fclose(file);
}
CLogManager* CLogManager::getInstance()
{
    if(logManager==NULL)
    {
        logManager = new CLogManager();
        logFileName = currentDateTime();
    }
    return logManager;
}
const std::string CLogManager::currentDateTime()
{
    time_t now = time(0);
    char currTime[30];
    strftime(currTime, sizeof(currTime), "Log_%Y_%m_%dT%H_%M_%S.xml", localtime(&now));
    return currTime;
}
void CLogManager::Log (char *message)
{
    file = fopen(logFileName.c_str(), "a+");
    if(file == NULL) 
    {
        if(fileOpenError == false) …
