FUNCTION

NAME
        call_other - Call a function in another object.


SYNTAX
        mixed call_other(object ob|object *ob|string ob, string func, ...)

DESCRIPTION
        This function is used to call another function in a given
        object or array of objects, If the object `ob' is given as a
        string, call_other tries to find it using 'find_object()'. If
        not found, call_other tries to load it, otherwise the object
        pointer or object array is used directly. If the object is 
        given as a string, the absolute path to the object must be
        given. `func' should simply be the name of the function to
        be called. Any number of arguments to the function can be
        added to the call. 'call_other()' can also be performed
        using the '->' operator. 


EXAMPLE
        name = (string)call_other(find_player("commander"), "query_real_name");
        access = (int)call_other("/secure/master", "valid_read", 
                                 "DONE", "commander", "my_func");


EXAMPLE
        name = (string)find_player("commander")->query_real_name();
        access = (int)"/secure/master"->valid_read("DONE", "commander", 
                                                   "my_func");


NOTE
        The default type of "call_other()" is unknown, but as shown in the
        examples above it is always possible to cast to a type of your
        own choosing, if nothing else only to aid memory.

	It is possible to feed the call_other efun an array of objects/strings
	in which to call the function. The driver then simply loops over the
	array, treating every object once. An array holding the results are
	then returned.
