5/22    Rephrased question: suppose you have new system header files.
        How do you change how the system searches for the default header
        files if you do not have root permission?
        \_ Rephrase it again, it's still not clear.  Header files for what?
                            \_ ;
           "system" searches for the default header files?  Do you mean
           how to change your compiler search order?  If you have new system
           header files, whoever installed them should've put them in the
           right place. -oj
           \_ #include <iostream.h> for example.  You have a new compiler
              you are trying out with a different iostream.h.  You want
              to make sure you are picking up the right iostream.h.  What do
              you do?
              \_ Take out the hostage.
                 \_ what movie did that come from again?
                    \_ The Netrix
              \_ Your new compiler should be using the new iostream.h if it
                 has one.  Otherwise read the man pages on how to set your
                 search path.  Since we're correcting, it's "shoot the hostage"
                 and it's from _Speed_. -oj
                      \_ Usual suspects had a very similar situation

1/14    Why is NULL defined to be "0" in C++ instead of "((void *) 0)" like in
        C?  I have some overloaded functtions where one takes an integer
        parameter and the other a pointer parameter.  When I call it with
        "NULL", the compiler matches it with the integer version instead of
        the pointer version which is a problem.  Other funny effect is that
        sizeof(NULL) is different from sizeof(myPtr).  Thanks.

8/31    I'm trying to learn ActionScript, like a step by step tutorial.
        The site at http://www.actionscript.org/resources/categories/Tutorials/Flash/Beginner
        isn't well organized. It doesn't explain how to get started with
        an editor, compiler, IDE. And should I even learn AS2 when you can
        learn AS3? Is Adobe Flash CS4 >>> CS3 or just CS4 > CS3?

2/28    I'm looking for a recommendation of a compiler/IDE to use to
        develop C/C++ code under Linux. In school, we used jove/gcc and
        I still use emacs/vi and gcc to this day. However, it is really
        lacking. Under Windows I tried Visual Studio and there were some
        really nice things about it, although it was so overwhelming that
        after 6 months of occasional use I still didn't really know what I

6/8     CSUA code guru please help. I need to see my random number
        generator with a good seed (I just need random 18 bit
        identifiers). The usual time(NULL) is OK, except my program
        might be invoked faster than once a second, and seeding using
        time() produced the same result. I tried clock() but it seems
        to return 0. My program needs to be run in Linux/DOS (Watcom

4/2     Is there an interpreted version of C or C++ that can be used for
        educational purposes? It doesn't have to be full-featured or
        strictly adhere to the standards, but it's painful for students
        to change a variable in a for loop and then wait for a compile
        to see how it changes the result. Something really lightweight
        would encourage them to play around a lot more and learn more in

11/27   I'm using select to do a nonblocking check to see if a single socket
        has anything to read off it.  Problem is, I can have up to 12228
        file descriptors, and Linux fd_set only supports up to 4096.  Any idea
        what I can do about this?  (Or a better solution?) -jrleek

11/10   Is there anyway to get C/C++ compilers to automatically compile
        different code for different processors?  I'd like to be able to
        say something like:
          #if defined X86 ...
          #elif defined SPARC ...
