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+):

            float f_value = 16777217.0;

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?

4/6     In C++, if there are several instances of an object, and for
        debugging purpose I want to see which instance of an object it is, I
        can do 'printf("%p", pObj);' to print out the address of the object.
        Is there any way to do something similar in C#?  Thanks.
        \_ CLR objects can get shuffled around in memory nondeterministically.

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.

2/17    This *has* to exist: I'm working w/ a text file that uses ascii #2
        for record separators and ascii #1 for field separators.  Is there
        a utility that will print out these ascii values for me, so I can
        (for example) use them with command line awk and perl scripts? Ex:
        fs=`atoi 1`
        perl -pi e's/(.*)$fs(.*)/$1$fsfoobar/g' myfile.txt

10/1    If i want to awk '{print $2+}' is there a way to do that without
        looping, or am i being TOO lazy?
        \_ perl
           \_ probably.  what are you trying to do in not-awk-speak?
           \- you can use this loop. there might be a range operator
              in some versions of awk, but not in generic awk. --psb

9/27    How are functions like C's printf made?  It can take 1-N arguments and
        the 2-N arguments can be of almost any type.  How do you write a
        function like that?  Surely printf wouldn't work with 500 arguments?
        \_ probably would, depends on how much stack you have.  See <stdarg.h>
        \_ man stdarg
        \_ Has to do with the ... function argument notation.  Check your

9/20    C question.  If I have

        is there any way to use NAME to create a string "FOO"?  Thanks.
        \_ Do you mean #define NAME "FOO" ?  Or do you want to declare a

        \_ 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
