potential memory leak in do loop

2006-05-02 Thread Stephane Chatigny
Hello,   I use the MIT MPB package on a machine running guile 1.6 and Debian-Linux 3.1r0a. Apparently, I generate a memory link while executing a do loop (although I have not tracked the memory usage yet). When I run the loop, the process is aborted before the end of the iteration. Inter

Hi, I am trying to add a new number class, export generic methods from a module and import them into another one. If I ignore the GOOPS tutorial and read only the reference, it is my understanting that I should do: ;; ;; exporting.scm (define-modul

passing flags to a function

2006-05-02 Thread Dan McMahill
Hello, I'm sure this is a very basic question about passing "or-able" flags to a function. In C I might do something like: #define FLAG_FOO 1 #define FLAG_BAR 2 #define FLAG_BAZ 4 myfn(int flags) { if (flags & FLAG_BAR) printf ("bar flag is set\n"); ... } and then call myfn
