Checks whether a screen is in the saved list

int sm_issv (char *screen_name);

screen_name

The name of the screen to search in the saved list.

• 1 True: The screen is in the saved list.

• 0 False.

sm_issv searches the list of screens saved in memory for the specified screen. Call this function on screen entry to avoid redundant database queries for previously saved screens:

1. On screen exit, call sm_svscreen to add the screen to the save list.
2. On screen entry, call sm_issv to check the save list, to ascertain whether the screen has already been displayed.

/* Perform database query only once */
	/* on the screen "results". */
	 
	if (!sm_issv("results"))
	{
	   /* do query . . .*/
	   sm_svscreen (screen_list, 1);
	}
