Setting the Checkmark Status of a Choice List Item
To set the checkmark status of an item in a multiple selection choice list, use the choice list item check function, cli_check():
void cli_check(state, item_num, clistp)
int state; /* State to set the checkmark: ON or OFF */
int item_num; /* Item number to set checkmark for */
CLISTPTR clistp; /* Pointer to choice list */
