Filtering the chat

[Matteo 46]

Hi,

Im trying with a function to filter some string from the chat, but it gives a strange error.

Functions:

const char* FilterChat(const char* c_pszBuffer)
{
    std::string strChatBuf = c_pszBuffer;

    // Other stuff with the string, but its commented out rn.
    
    char szTmpBuf[1024 + 1] = {};
    const char* c_szpFilterBuf = strChatBuf.c_str();
    _snprintf(szTmpBuf, sizeof(szTmpBuf), "%s", c_szpFilterBuf);

    return szTmpBuf;

}

In bool CPythonNetworkStream::RecvChatPacket():

#ifdef CHAT_FILTER
	CPythonTextTail::Instance().RegisterChatTail(kChat.dwVID, FilterChat(line));
#else
	CPythonTextTail::Instance().RegisterChatTail(kChat.dwVID, line);
#endif

 

And in-game its junk:

 

What's the problem? With debugging it seems the array gets created with full of junk already, but i've initialized it with full of zeroes if im not wrong.

Use a static variable instead for szTmpBuf.

static char szTmpBuf[1024 + 1] = {};

for better;

constexpr char szTmpBuf[1024 + 1] = {};

or:

That's a small tip for the next time when you're coding, so you'll know if it's a critical warning and it needs real attention or not, based on the level.
