创建日志文件win 32 [英] creating log file win 32

问题描述

void dshowCapture::initlogfile()
{
    /////////log file initialization////    
    TCHAR dwDirectory[256];
    TCHAR capturelogfile[256];
    ZeroMemory(dwDirectory, sizeof(dwDirectory));
    ZeroMemory(capturelogfile, sizeof(capturelogfile));
    GetCurrentDirectory(256, dwDirectory);
    strcpy (capturelogfile,dwDirectory);	
    strcat(capturelogfile,"\\CaptureLog.txt");

    std::ofstream *fs;
    fs=new	std::ofstream(capturelogfile); 

    char *log="helow";

    for(int i=0;i<1000;i++)
    fs->write(log,sizeof(log));

    fs->close();
    delete fs;

}

这是正确的实现，因为程序运行但在
之后

Is this correct implementation because program runs but after

std::ofstream *fs;
fs=new	std::ofstream(capturelogfile);

大约48个字节，在执行for循环后增加50个字节

删除操作后，内存保持增加的值(大约100字节左右).

near about 48 bytes and after execution of for loop 50 bytes increase

after delete operation memory remains to that increased value(near abt 100 bytes)

推荐答案

虽然我对代码有很多注释，例如制作TCHAR数组和使用strcpy代替_tcscpy或更好的_tcscpy_s，但显然您可以编写指针的大小(好东西，您在此不使用64位)大小写)到文件；我无法直接看到内存泄漏的出现.

请注意，如果您的应用程序泄漏，则在关闭应用程序时，很可能会在输出窗口中看到正在转储正常阻止"通知.

干杯，

Hi,

Though I have a number of comments to the code like making TCHAR arrays and using strcpy in stead of _tcscpy or bettery yet _tcscpy_s and apparently you are ok wiht writing the size of a pointer (good thing you''re not using 64 bits in this case) to the file; I can''t directly see a memory leak appearing.

Note that if your app is leaking you will most likely see a "dumping normal block" notification in the output window when closing the app.

Cheers,

AT.
