Just to be correct, since only 1 statement is being used, the { } is   
optional.  The real problem is that in C you can't do a string comparison   
with the == operator.  A small criticism is that you probably wouldn't   
want to pass a struct by value.  Also, you're showing DOS origins; in   
Unix the prototype for main() is "int  main(int argc, char** argv, char**   
env);"  So, with corrections and embelishments (details of   
get_book_info(), buy(), and pshaw() are left to the imagination):


#include <string.h>
#include <stdio.h>

struct tmoney
{
    int dollars;
    int cents;
};

typedef  struct tmoney t_money;

struct tbook
{
    char    title[64];
    char    author[64];
    char    publisher[64];
    t_money  MSRP;
};

typedef struct tbook t_book;

struct terror
{
    int    errno;
    char  message[128];
    int    severity;
};

typedef struct terror t_error;

t_error  get_book_info(t_book*  book);
void  buy(t_book*  book);
void  pshaw(t_book*  book);

int
main(int argc, char** argv, char** env)
{
t_book  book;

    get_book_info(&book);

    if (strcmp(book.publisher, "oreilly") == 0)
        buy(&book);
    else
        pshaw(&book);

    return 0;
}

just to be pickey

void main (void) {
        if (book.publisher == "oreilly") {
                buy(book);
        } else {
                pshaw(book);
        }
        return;
}

hehe.. if someone wants to write the rest of the program for this.. i bet   
it
would be a nice sub-page off of the tclug web page
