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