Thread: program structure with select sockets

I understand your problem, but you need to understand, that Microsoft didn't create socket programming, it's just the same.
I believe the guide contains a section explaining how to make the functions to work under windows, please read it!

But any way, the examples work, trust me on that one, the only thing that could be a problem for windows is fork() which is nothing more than a new child process "creator", but is not supported by windows.


As for a command line program, I can't believe you did API before simple command like applications.

Just remember to keep looping, set a timeout timer for select and avoid getting to the blocking functions, unless you have incoming data which will not make the functions to block. And each time select timeouts display a message.
Go through the example again; As far as I remember it works on windows.

This was an example of the implementation of select() in Beej's code;

Code:

/*
** select.c -- a select() demo
*/

#include <stdio.h>
#include <sys/time.h>
#include <sys/types.h>
#include <unistd.h>

#define STDIN 0  // file descriptor for standard input

int main(void)
{
    struct timeval tv;
    fd_set readfds;

    tv.tv_sec = 2;
    tv.tv_usec = 500000;

    FD_ZERO(&readfds);
    FD_SET(STDIN, &readfds);

    // don't care about writefds and exceptfds:
    select(STDIN+1, &readfds, NULL, NULL, &tv);

    if (FD_ISSET(STDIN, &readfds))
        printf("A key was pressed!\n");
    else
        printf("Timed out.\n");

    return 0;
}

I don't like to copy code, so i tried to write my own code from looking at that, but it didn't work, so i tried copying the code, and that didn't work either, my compiler doesn't recognize any of the "FD" commands. this is all the code, and it was linked to w2_32.lib.

Edit: because it seems that those FD commands are all over his code, i got discouraged and gave up on his tutorial.
