/*
* Name: add_string.c
*
* Description: Add a string to a menu object. Allocates a menu
* string structure using menu_alloc() and initializes the fields.
* Returns a pointer to the menu string.
*
* There are several ways to add strings to menu objects.
*
* 1) A separate routine could be written for each object.
* This would be would allow only the needed routines to
* be loaded.
* 2) The address of the menu_string list for the object
* could be passed as a parameter. This was tried in
* an earlier version of the library, but has been
* discarded as too messy.
* 3) A generic object pointer could be passed. The routine
* could decode the object pointer and the menu string
* could be added to the appropriate place.
*
* The final solution was chosen. This implementation does
* not cause any extra routines to be loaded and it does not
* require numerous routines.
*
* Call syntax: string_p = add_menu_string(obj_p, active, y_coord,
* x_coord, attribute, data_p);
*
* Parameters: pointer * obj_p;
* char active;
* menu_coord y_coord;
* menu_coord x_coord;
* menu_attr attribute;
* char * data_p;
*
* Return value: menu_string * string_p;
