RE: Memory Mapped files

You can use:

ccl:map-file
ccl:unmap-file

	"Usage:  (MAP-FILE pathname)
	     Returns (1) address of the memory mapped file (or null if
an error occurred)
	             (2) the length (in bytes)"

Just pass unmap-file the returned address from map-file when you are
done with it.

File-mapping is used for some things in corman lisp, such as reading of
compiled files.
You need to use ffi functions to deal directly with the memory returned
via pointers.

Subject: [cormanlisp] Memory Mapped files


Hi:

I have a question to this group. :=)
Can Corman common lisp use memory mapped files?
I know you can do this trough API calls. Unfortunately i am a newbie 
and this method using API calls seems complicated. 
Is there a book that explains how-to? 
Is this something that can be easily implemented in corman common 
lisp?

Thank you
