    Sometimes, your computer may display an error indicating a write error for socket C. There can be several reasons for this problem.

    No problem, the most important one is that you are probably moving garbage data to the make socket using sizeof (buffer) when composing. Let’s say you are reading data from socket Reads and not MAX_LINES. If you write it down positively, you will be happy with everything you read, plus the garbage at the end of the barrier (although you will no doubt have a memset at the very beginning, continuing to use every same buffer without reacting differently, you will be able to read sizes that can generate a lot of spam.

    Try to remove the return value from reading and use it in your real write. If a read back indicates an error, perhaps clear and exit, or try again, depending on how your program works best.

      integer n, size;during (1)   size = read (read, buffer, sizeof (buffer));   if (size> 0)       n = write (write, buffer, size);       if (n! = size)           // build fails, do something             different       // read the error, do something    

    Of course, this assumes that your writes are combined with reads are valid file descriptors.

    Programming sockets in C or C ++ can be tricky. One thing you can do to make it happenit is easier to implement a decent error maneuver. It can be difficult sometimesbecause Windows handles errors differently than Linux or macOS.

    Get Error Code

    On Linux or macOS, the last error is necessarily recorded in the errno variable. ToWindows, you can get the latter error by calling WSAGetLastError () . to callFunction. You will almost certainly need your own program if you need to check for errors.I recommend these wrapping methods in a macro several times.

    The following code defines a callable function macro that returns getsocketerrno () extreme error code.

    // Cross-platform error code# if defined (_WIN32)#define GETSOCKETERRNO () GETSOCKETERRNO () (wsagetlasterror ())#different#define (error)#end if

    Now if you are talking to a function like socket () you can find it and display itpassword error is easy. For example, shortly thereafter, tood will lead to the wrong choice andprint error 0, code:

    Taken (0, 0); // can certainly lead to an error!printf (“The last error was% d n”, GETSOCKETERRNO ());

    This is an easy way to get the error code, but what abouta descriptive error message?

    Error Messages Received On Linux / MacOS

    It’s easy to get an error message on Linux or macOS. Only you comenumerous errno for the strerror () function.

    printf (“Last error message:% s n”, strerror (errno));

    Receive Error Messages On Windows

    Getting a match error on Windows is a little trickier. you wantUse FormatMessage () for the actual function and this function is … tricky.

    c socket write error

    Instead of explaining all the parameters associated with FormatMessage () , it’s easier to pass themjust an example for you.

    The following code tends to print the final error speech for your program on Windows:

    static message character [256] is 0;Format message ( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, WSAGetLastError (), 0, 9, message, 256, 0);printf (“Last error message:% s”, c communication);

    Keep in mind that FormatMessage ideas usually start with a file. Returnthe end-of-line character at the most important end.
