I'm trying to emit a signal which contains three string arguments, however, I'm having issues when compiling. I am defining the signal as follows:    signals [NAME_OF_SIGNAL] =   g_signal_new ("name-of-signal",          G_TYPE_FROM_CLASS (object_class),          G_SIGNAL_RUN_LAST,          G_STRUCT_OFFSET (MyClass, name_of_signal),          NULL,          NULL,          g_cclosure_marshal_VOID__STRING_STRING_STRING,          G_TYPE_NONE, 2, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING);   However, when trying to compile this code I get the following error.    error: 'g_cclosure_marshal_VOID__STRING_STRING_STRING' undeclared (first use in this function) I'm guessing that this isn't the correct notation for a three string marshal, so what is?   Thanks for your advice guys, sorry for the dopey question, I'm new to this.   Robert <hr />A prize an hour, 24 hours a day. <a href='http://www.bigsnapsearch.com ' target='_new'>Try Big Snap now!</a></body> </html>
