Filling the first word of the buffer

MSDN says to use the EM_GETLINE message to get the text of an edit, you have to "set the first word of this buffer to the size, in TCHARs, of the buffer". It seems to work without doing so, but am I doing this right?

Code:

---

        int length = 0;
        char * pchText = NULL;
        WORD mp = (WORD)MAX_PATH; \\???

        pchText = (CHAR*)HeapAlloc(GetProcessHeap(), 0, MAX_PATH);
        CopyMemory(pchText, &mp, sizeof(WORD)); \\???
        length = SendMessage(g_hSource, EM_GETLINE, 0, (LPARAM)pchText);
        pchText[length+1] = '\0';
        MessageBox(0, pchText, "test", MB_OK);
        HeapFree(GetProcessHeap(), 0, pchText);

Thanks.

Yeah, this is right. I don't know about intel byte order, butI think windows can handle this.

Ok, thanks.
