Hello, If I have a C function which allocates memory for a C string and returns a pointer to this memory (return type char *).
Should the return type of this function be :string or :pointer?
How do I deallocate this memory? Should I use `foreign-string-free' or `foreign-free'.
Is there any way this deallocation can be made automatic? Say, something similar to clisp's `:malloc-free', or should I copy this foreign string as a lisp string and then free the foreign string.
Thanks.
