9/10    Stupid question: how do I reference a C callback?
        int mycompare(void const *a, void const *b) { ... }
        qsort(msg, sizeof(Msg), numMsgs, mycompare);
        I get
        "Type error in argument 4 to `qsort'; calling convention mismatch."
        \_ There's nothing wrong in the you reference it.  However, you should
           make the mycompare() prototype match exactly with what qsort() wants
           in its prototype.  Exactly what it wants depends on your machine
           and your compiler.  Check the .h file that you're including.
           \_ Yeah, I just realized that it compiles w/ gcc... I have some
              problems, apparently. --op

3/7     I have a C question.  I have the following source code in two identical
        files t.c and t.cpp:
                #include <stdlib.h>
                int main(int argc, char *argv[]) {
                  const char * const * p1;

8/10    C question.  Is there anything wrong with the following?
        const my_struct_t **pp;
        pp = malloc(sizeof(my_struct_t *));
        pp = realloc(pp, sizeof (my_struct_t *) * 2);
        "gcc -Wall" doesn't complain.  But the M$ compiler (cl.exe) complains
        about the realloc line:

12/8    c++ question, how do I overload << in my class so it will handle
        endl? ie: myclass << "some string" << endl
        I know how to do the "some string" part:
                myclass & operator << (const char * s);
        what about endl?
        Thanks!!

7/13    how do i pass variables to the system in C ?  e.g.
         system("echo input is %s", argv[1]);
        results in "input is %s" but I want the system to see argv[1]
        (I know i can just use printf, but not for what i really want to do).

9/23    let's say there's a C library you want to use called libmdn.so.
        I think to load it you'd go something like:
        static { System.loadLibrary("mdn"); }
        However, let's say that a function call looked like this:
        mdn_result_t mdn_encodename(int actions, const char
        *from, char *to, size_t tolen)

3/16    Why does so much C sample code use #define instead of const?
        \_ because any good C code will use a bunch of preprocessor
           anyways. you can't be a good C programmer and eschew the
           preprocessor. For that, you need a language which fills those
           gaps with other constructs (c++ templates go a long way to
           obviate the need for preprocessor for example). you

6/20    I have a variable inside a struct.  I want to be able to initialize
        that variable ONCE and not write to it again.  Any subsequent writes
        should not be permitted.  Is there a way to do that in C?  I know
        about "const int foo = 5;" but the value I need to pass in is dynamic
        and happens at runtime.  Declaring a variable as const doesn't let
        me assign anything to it at all.  Thanks.

4/26    Any recommendations for good questions to ask for live interviews
        for a C/C++ coder position?  We're having some tomorrow and I
        wanted to see what people thought.  We don't want geniuses; just
        bright people who have good habits.  E.g., questions one or two
        difficulty levels below asking them to compare timings for
        common sort alogorithms.
