- (callback-set! [handle ihandle?] [name (or/c symbol? string?)] [proc (or/c procedure? pointer? #f)]) -> void?procedure
Associates a procedure with a callback of an object.
Alternatively:
(set! (callback [handle ihandle?] [name (or/c symbol? string?)]) [proc (or/c procedure? pointer? #f)])
Note that the current CHICKEN implementation allows native pointers to be passed as callback procedures.
