Clarion in general: Memcpy to get a value from an address 2004-03-11 -- Paul Attryde Newsgroups: softvelocity.clarion.language > I am calling a function that returns that address of a memory location. > How do I get the contents of that location when all I have is the address? So you're doing something (making an API call for example) and getting back a pointer? But because CW doesn't support pointers you can't dereference it? There's a couple of ways to do it. You can do what Bernie suggested and use a reference variable (but that assumes you're using a version of CW that supports reference variables, and this is softvelocity.clarion.language, not softvelocity.public.clarion6) Personally I use memcpy, only because I've been doing this for a while and CW2 didn't have reference variables :) http://www.attryde.com/clarion/cw_prototypes.htm, #8 ISTR Randy Goodhew saying you can do it using PEEK as well, but I've never used that. You may have to search the NGs for more info. -- Paul Printed May 6, 2024, 8:44 am This article has been viewed/printed 35118 times.
