The following functions accept a structure name as the only argument.
If DEFSTRUCT was given the :TYPE option (i.e., DEFSTRUCT did
not define a new type), then (FIND-CLASS name)
fails (and the regular CLOS Meta-Object Protocol is not applicable), but these
functions still work.
EXT:STRUCTURE-SLOTS- Return the
LIST of effective slot definition metaobjects.
EXT:STRUCTURE-DIRECT-SLOTS- Return the
LIST of direct slot definition metaobjects.
EXT:STRUCTURE-KEYWORD-CONSTRUCTOR- Return the name (a
SYMBOL) of the keyword
constructor function for the structure, or NIL if the structure has
no keyword constructor. EXT:STRUCTURE-BOA-CONSTRUCTORS- Return the
LIST of names (SYMBOLs)
of BOA constructors for the structure. EXT:STRUCTURE-COPIER- Return the name (a
SYMBOL) of the copier for the
structure. EXT:STRUCTURE-PREDICATE- Return the name (a
SYMBOL) of the predicate for
the structure.
