Re: [Lush-users] wrapping C libraries for use in lush, macros, and parsing

[Jason E. A. <j.e...@gm...>]

Quick question (perhaps the manual is out of date on this) -- I couldn't
seem to load or locate the sources for the lisp-c-map function.

I had guessed that given how (lisp-c-map) is  described in the manual at
"8.8.3 Controlling the Lisp/C Interface", it would be helpful in
understanding the current memory conventions for C and lisp objects.  But
does this function still exist?  If not, is there a replacement, or how
should I load it.

Thank you.

Jason
