I’ve created an After Effects script that extracts data from JSON files downloaded from an HTTPS URL. The problem is with the C++ DLL I’ve coded to download it and pass it back to the script. Even though it has been working fine, there was one instance of memory leak — After Effects issued a popup saying, «STRING MEMORY LEAK».

I’m new to C++ but I’ve managed to compose a DLL that downloads the files based on the examples provided with the After Effects installation (samplelib and basicexternalobject) as well as by Microsoft’s C++ documentation. The Adobe JavaScript Tools Guide says that the method «ESFreeMem()» must be «called to free memory allocated for a null-terminated string passed to or from library functions». The problem is I don’t know how or where to use it. I’m using After Effects CC 15.0.0 (build 180) on Windows 7.

This is the C++ function that gets some parameters from the javascript caller and returns a string with the JSON contents. If it fails it returns a bool (FALSE) so that the script can do what is necessary in this case.

extern "C" TvgAfx_Com_API long DownloadJson(TaggedData* argv, long argc, TaggedData * result)  
{  

     //... first I check the arguments passed  

// The returned value type  
result->type = kTypeString;  


//Converts from string into LPCWSTR ---------------------------------------------------  
std::wstring stemp = s2ws(argv[0].data.string);  
LPCWSTR jsonLink = stemp.c_str();  


std::wstring stemp02 = s2ws(argv[1].data.string);  
LPCWSTR jsonHeader = stemp02.c_str();  
//--------------------------------------------------------------------------------------  


//Class that does the HTTP request  
WinHttpClient client(jsonLink, jsonHeader);  


//Synchronous request   
if (client.SendHttpsRequest())  
{  
     string httpResponse = client.GetHttpResponse();  


     if (httpResponse.length() > 0)  
     {  
          //Sends response string back to javascript  
          result->data.string = getNewBuffer(httpResponse);  
     }  
     else  
     {  
           //Sends FALSE back to javascript  
           result->type = kTypeBool;  
           result->data.intval = 0;  
     }  
}  
else  
{  
     //Sends FALSE back to javascript  
     result->type = kTypeBool;  
     result->data.intval = 0;  
}  


return kESErrOK;  
}  

The class WinHttpClient that does the actual request frees the memory allocated to the buffer that holds the response. Here’s a piece of code:

// Read the data.  
ZeroMemory(pszOutBuffer, dwSize + 1);  

if (!WinHttpReadData(hRequest, (LPVOID)pszOutBuffer, dwSize, &dwDownloaded))  
{  
//Log error  
}  
else  
{  
resource.append(pszOutBuffer).c_str();  
}  


// Free the memory allocated to the buffer.  
delete[] pszOutBuffer;  

This is the function that the Adobe example uses to hold the string that will be returned to javascript:

//brief Utility function to handle strings and memory clean up  
static char* getNewBuffer(string& s)  
{  
// Dynamically allocate memory buffer to hold the string   
// to pass back to JavaScript  
char* buff = new char[1 + s.length()];  


memset(buff, 0, s.length() + 1);  
strcpy(buff, s.c_str());  


return buff;  
}  

Now, the manual says this method must be implemented:

/** 
* \brief Free any string memory which has been returned as function result. 
* JavaScipt calls this function to release the memory associated with the string. 
* Used for the direct interface. 
* 
* \param *p Pointer to the string 
*/  
extern "C" SAMPLIB void ESFreeMem (void* p)  
{  
if (p)  
free (p);  
}

What I understand from this is that the memory associated with the json string returned must be released. But didn’t the request class already do it? I just don’t know where to call this method and what to pass on to it. I would appreciate any help. Thanks a lot!
