Like this, it worked without problems.
void iupDlgListDestroyAll(void)
{
int i, count = 0;
Ihandle** ih_array = (Ihandle**)malloc(idlg_count * sizeof(Ihandle*));
Idiallst *list;
for (list = idlglist; list; list = list->next)
{
if (iupObjectCheck(list->ih))
{
ih_array[count] = list->ih;
++count;
}
}
for (i = 0; i < count; ++i)
{
IupDestroy(ih_array[i]); /* this will also destroy the list */
}
free(ih_array);
}
Advantagens:
1. Avoid assign variable count with i value;
2. Avoid call iupObjectCheck for every ih_array[i], since they have all been
verified.
