[cffi-devel] automatic conversion of array of (unsigned-byte 8) to c-string
this is exactly the example from the manual: (let ((str (make-array 4 :element-type '(unsigned-byte 8) :initial-element 65))) (foreign-funcall "strlen" :string str :int)) but my lisp says: #(65 65 65 65) is not a Lisp string or pointer. [Condition of type SIMPLE-ERROR] What is going on? This works as expected: (let ((str (make-array 4 :element-type 'character :initial-element (code-char 65)))) (foreign-funcall "strlen" :string str :int)) => 4 I run clozure cl on windows 32

This used to work but it stopped making much sense when we added support for string encodings. I've fixed the manual and will upload it as soon as I figure out how to build it on OSX. -- Luís Oliveira http://r42.eu/~luis/

Do you mean all the :string conversions, or only :string used with unsigned-byte 8?

The latter. Cheers, -- Luís Oliveira http://r42.eu/~luis/
