/* Name: AppendWinRegString
 *
 * Arguments:
 *
 * HKEY hkRootKey -- root key, e.g., HKEY_LOCAL_MACHINE
 * LPSTR szKey -- subkey
 * LPSTR szName -- value name
 * DWORD dwType -- value type, should be REG_SZ
 * LPBYTE lpbData -- value data
 * BYTE delimiter -- e.g., ':'. If 0, then don't apply delimiter
 * DWORD dwSize -- size of the value data
 * BOOL bLogForUninstall -- if true, update install log
 * BOOL bDnu -- what to update the install log with
 *
 * Description:
 *
 * This function should be called to append a string (REG_SZ) to the
 * string already stored in the specified key. If the key does not
 * exist, then simply store the key (ignoring the delimiter). If the
 * key does exist, read the current value, append the delimiter (if
 * not zero), and append the data passed in.
