Re: How do I write wrapper for foreign-alloc, that frees it.

well i noticed even creating a million of them(foreign-alloc) doesnt make my ram go up, and when I am done using the matrix eg it is deleted(my matrices are created with a new operator) the data is still in the pointer created by foreign-alloc, I was hoping to free that data automatically when the m...

How do I write wrapper for foreign-alloc, that frees it....

automatically when it goes out of scope(or the functions that can still access the data created by foreign-alloc go out of scope). I'm trying to write a loose wrapper for cffi:foreign-alloc that finalizes(calls cffi:foreign-free on it) it automatically. For instance if I have a defcfun named "test" ...

Re: How can I call CL:GET in a condition statement

If I can get this to work this will be where it is defined:

Code: Select all

(defun get1 (&rest args)
  (cond ((symbolp (first args))
    (apply #'cl:get args))
   ((typep (first args) 'cv-video-capture)
    (princ 1))))

Here is my cond statement, to make it simpler I took ot the code that was where the (princ 1) and just added my CFFI type for cv-video-capture at th ebottom because I think it might be relevant. It might make things more confusing to say why I would like to do this, so I just will say it is neccessa...
