Where is the exact code part of the walletnotify function?

I don't know exactly what you are asking, but

wallet.cpp (from line 591)

    // notify an external script when a wallet transaction comes in or is updated
    std::string strCmd = GetArg("-walletnotify", "");

    if ( !strCmd.empty())
    {
        boost::replace_all(strCmd, "%s", wtxIn.GetHash().GetHex());
        boost::thread t(runCommand, strCmd); // thread runs free
    }

runs a thread that executes the runCommand() function in util.cpp

wallet.cpp (from line 1335)

void runCommand(std::string strCommand)
{
    int nErr = ::system(strCommand.c_str());
    if (nErr)
        LogPrintf("runCommand error: system(%s) returned %d\n", strCommand, nErr);
}

and I think that is all code you need.

I know this part when I do the search in the entire project. But what I don't get is when I typed the command "bitcoind -walletnotify", there should be have a function named like "walletnotify()" or something similar to send back these incoming transactions that hits the addresses in my wallet.

I'm trying to find this function and make some modify to its if conditions and return(or echo) form; – Kaninchen – 2014-06-24T15:45:53.587

There is no walletnotify() function. All logic is in these two snippets. – Jori – 2014-06-24T19:32:38.443

Hmm, sad they didn't make it a function... Thanks and I'll ask again if I got more questions. – Kaninchen – 2014-06-25T07:15:47.600

A good place to start: https://github.com/bitcoin/bitcoin/blob/master/src/wallet.cpp#L591

Instead of modifying the actual bitcoin code, which is often very error prone, it may be better to trigger some api request upon walletnotify. – Loourr – 2014-07-05T20:31:33.287
