7/19    In C or C++, how do I write the code of a function with variable
        number of parameters in order to pass the variable parameters to
        another function that also has variable number of parameters?  Thanks.
        \_ The usual way (works on gcc 3.0+, Visual Studio 2005+):
               #define foo(fmt, ...) printf(fmt, ##__VA_ARGS__)
           The cool new way (works on gcc 4.3+):

2/4     random C programming/linker fu question.  If I have
        int main() { printf("%s is at this adddr %p\n", "strlen", strlen); }
        and soda's /proc/sys/kernel/randomize_va_space is 2 (eg; on)
        why is strlen (or any other libc fn) at the same address every time?
        \_ I don't pretend to actually know the right answer to this, but
           could it have something to do with shared libraries?

7/13    How do you get milliseconds in C? I want to do something like:
        t1=sec;
        long_operation_that_needs_to_be_benchmarked();
        t2=sec;
        printf("This operation took %f seconds", (t2-t1));
        \_ You could try using clock() and CLOCKS_PER_SEC.

6/21    My math and/or perl fu is weak. Is there a way to get integer
        multiplication in Perl the way it's done in C? i.e. limiting
        to 32 bits. Like 1588635697 * 1117695901 = 1166976269 in C.
        \_ Can't you just multiply and then mask all but the last 32 bits?
           \_ I don't think so; that's not the same as mult overflow.
              > perl -e 'print (1588635697 * 1117695901)'

5/12    nCircle is looking for an experienced software engineer.  See
        /csua/pub/jobs/nCircle.sweng
        \_ so I have been doing java, and I still believe I'm an expert
           c/c++ programmer.  However, if you ask me what are
           the printf format parameters, I doubt I could tell you much
           other than %s.  So I can definitely get a book on c/c++ and

5/10    Can I create arbitrary blocks of code in C without control structures?
        I really just want something I can "break" out of.
        GetLock(myLock);

          rc = SomeLibraryCall();
          if (rc < 0) break; // breaks to release lock

            printf("\n\n0x%x %d", ptr++, *ptr);
        }
        Is there anything machine dependent about the evaluation of ptr++?

11/17   How come printf("%f\n", 1/10); returns 0.000000?

              spoon feed someone on the motd.  I'll bet you're not a pine

7/13    how do i pass variables to the system in C ?  e.g.

        (I know i can just use printf, but not for what i really want to do).

10/25   Simple question..  In C under unix, how do I invoke the unix command
        date to create a char string which contains the present date?
           \_ actually, you should fork a process that runs date
              but has date's stdout handle to point to a handle in the
              parent proc.  yeah, you really want time(), ctime()
