Re: g_list_first()

[Elmano Carvalho <elmano carvalho gmail com>]

Hello guys,

thanks for the help as I was able to get a better idea of how to solve this problem. 
And indeed I was able to devise something that seems to do the job.

Hello, What did you need to do exactly????

If you need to test all elements in a single list and delete elements you
whish you can use this type of code, it isn't optimised but it work's, else
you can use g_list_foreach to apply a personnal function at each element of
your GSList but it doesn't work for deleting GSList.
If you need any explanation mail me.

static GSList* _your_function(GSList* list, gint X)
{
GSList *saveList=list,*buflist=list;

while(list)
{
      if(  your_test  )  //(list->data < X) for example
      {
            gfree(list->data);

            if(list==buflist)  // case of first element of the list, we don't loose
the begin of the list
            {
                saveList=list->next;
                buflist=list->next;
                gfree(list);
                list=buflist;
            }
            else
            {
                buflist->next=list->next;      //if you need to free the list,
update the next element of the preceding list
                gfree(list);

                list=buflist->next;
            }
      }
      else
      {
            buflist=list;
            list=list->next;
      }
}

return saveList;
}
