Hi, I'm trying to create a simple ping routine, that can be used in other programs to test internet connectivity. I'm stuck, as the following code seems to send the request, but `recvfrom` blocks forever. Since I don't normally deal with sockets like this, I'm completely lost as to what is wrong. And I don't think I can look at more code that doesn't satisfy my need. Here's what I have: Code: // Declare includes. #include <arpa/inet.h> #include <errno.h> #include <fcntl.h> #include <libgen.h> #include <netinet/in.h> #include <netinet/ip_icmp.h> #include ..read more

Hi everyone, I'm learning about how computer memory works in C programming. Can you share how you figure out where things go in memory when you write C code? What tools or methods do you use to understand this? Thanks for your help ..read more

I'm not sure I really get the difference between NULL, (void *)0 and (char *)0. According to the C standard: Quote: An integer constant expression with the value 0, or such an expression cast to type void *, is called a null pointer constant. Quote: The macros are NULL which expands to an implementation-defined null pointer constant; and So does that mean that those values can be used on pointers of any type? For example, are these valid null pointers?: Code: #include <stdio.h> struct book {     char title[25];     char author[25]; }; int main(void) {   ..read more

Everyone, I wrote this trivial program in minutes to see how well it would come out. I produces the correct answers. But I don't know how to plug the memory leak Splint found. Would you please tell me how to solve the problem. If you think I caught OCD, you're. right. I'd hate to hear Splint complain about anything. That's why I assign function values to integer variables when most programmers wouldn't do that. Code: #define MAXNUMS 30#include <stdio.h> #include <string.h> #include <stdbool.h> static bool between(const unsigned int low,  const unsigned int high, co ..read more
