I expect the string is being freed or deallocated somehow before the
main thread sees it. Try something like:
In the worker thread context:
for(;;) {
char *data = g_malloc( lots of stuff );
fill_with_information( data );
g_idle_add( update_gui, data );
}
update_gui will run in the main thread context and can make GUI calls:
gboolean update_gui( char *data )
{
// this llooks through data and pdates the GUI
update_display( data );
g_free( data );
// returning FALSE removes this idle handler
return( FALSE );
}
I guess you might want to limit the number of update-gui()s that can
queue up, but that's a fine-tuning thing.
