Here we go again After successfully wrapping freexl_open, I can't do the same with freexl_get_info
One of the arguments expected by such function is "unsigned short" When I load the namespace at the REPL I get scheme@(guile-user)> ,m (freexl common) While executing meta-command: ERROR: In procedure pointer->procedure: Wrong type argument in position 3: int I tried with uint8, uint16 and uint32, with the same result Here's the function I'm referring to https://www.gaia-gis.it/gaia-sins/freexl-1.0.1-doxy-doc/html/freexl_8h.html#ad6dbe072c7a4632853d90f4509bf3aee And here's my code (there are some instructions as comments in the code) https://gitlab.com/humanitiesNerd/guile-freexl And here's an excerpt (define freexl-get-info (let* ((ptr (freexl-func "freexl_get_info")) (proc (pointer->procedure int ptr '(* int *))) ;;the int in the arguments list generates ;;a wrong argument type error when ;;loading the namespace at the REPL, like this ;;scheme@(guile-user)> ,m (freexl common) ;;While executing meta-command: ;;ERROR: In procedure pointer->procedure: Wrong type argument ;;in position 3: int ) (lambda (handle-ptr what) (let* ((outcome-ptr (bytevector->pointer (make-bytevector (sizeof '*)))) (result (proc handle-ptr what outcome-ptr))) (if (not (= result 0)) (throw 'get-info-error 'error-code result) outcome-ptr) )))) Thanks in advance
