With the compiler keyword 'calleradresstable'; function s( str : pchar ) : pchar; calleradresstable; Then the compiler makes a table of all calleradresses and also the amount of s() in the program. With the rtl function getcalleradresstable() then I get a pointer and the amount of the array. > I can see 2 ways you get that address > > procedure p (snip:string); > begin > calleraddr := get_caller_addr(); //needs to be implemented > ...... > end It exists already: http://www.freepascal.org/docs-html/rtl/system/get_caller_addr.html > OR > procedure p (snip:string, caller_addr:pointer); > .... > and when calling > p('hello world', get_my_addr()); // needs to be implemented > > *** BUT > then you run your app. You collect maybe (for example) 42 addresses with > snippets > > How do you know that is all of them?

I have yet to know, how that works with the caller address http://www.freepascal.org/docs-html/rtl/system/get_caller_addr.html _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
