I have a few questions about this patch. (defun pointer-eq (ptr1 ptr2) "Return true if PTR1 and PTR2 point to the same address." - (= (ffi:pointer-address ptr1) (ffi:pointer-address ptr2))) + ;; In ECL two pointers are EQUAL if they point to the same address. + (equal ptr1 ptr2)) One advantage of the previous definition is that passing non-pointers to POINTER-EQ would (I assume) signal an error. What do you think? +(define-compiler-macro null-pointer () + '(si::allocate-foreign-data :void 0)) Any reason why a simpler (declaim (inline null-pointer)) wouldn't work just as well? -- Luís Oliveira http://r42.eu/~luis/ _______________________________________________ cffi-devel mailing list cffi-devel@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/cffi-devel
