.DT replaceable $MUDNAME$ driver help replaceable .SH Name .SI 5 replaceable() - determine whether any functions are defined at this level .EI .SH Synopsis .SI 5 int replaceable( object ob ); int replaceable( object ob, string *fnames ); .EI .SH Description .SP 5 5 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. .EP .SH See also .SI 5 replace_program(), create() .EI
