Name
replaceable() - determine whether any functions are defined at this level
Synopsis
int replaceable( object ob );
int replaceable( object ob, string *fnames );
Description
In the second form, return 0 if the program for object `ob' defines any functions explicitly, as opposed to simply inheriting. Function names in the array `fnames' are ignored. If no such functions are defined, 1 is returned. If the second argument is omitted, it defaults to ({ "create" }). The purpose of this efun is to assist in making automatic decisions on whether to call replace_program(). Note that the default version ignores create(), so it is only safe to replace a object for which replaceable() returns true if you never intend to clone from that object.
