|

Overview About Socket Error Handling
|
||||
------------------------------------
|
||||
|
||||
Socket error handling code is very important for robust socket applications. Normally the socket error handling involves the following aspects:
|
||||
|
||||
- Detecting the error.
|
||||
- Geting the error reason code.
|
||||
- Handle the error according to the reason code.
|
||||
|
||||
In LwIP, we have two different scenarios of handling socket errors:
|
||||
|
||||
- Socket API returns an error. For more information, see <`Error Handling of Socket API`_>.
|
||||
- ``select(int maxfdp1, fd_set *readset, fd_set *writeset, fd_set *exceptset, struct timeval *timeout)`` has exception descriptor indicating that the socket has an error. For more information, see <`Error Handling of Select`_>.
|
||||
|
||||
Error Handling of Socket API
|
||||
++++++++++++++++++++++++++++
|
||||
|
||||
The error detection
|
||||
- We can know that the socket API fails according to its return value.
|
||||
|
||||
Get the error reason code
|
||||
- When socket API fails, the return value doesn't contain the failure reason and the application can get the error reason code by accessing errno. Different values indicate different meanings. For more information, see <`Socket Error Reason Code`_>.
|
||||
|
||||
Example::
|
||||
|
||||
int err;
|
||||
int sockfd;
|
||||
|
||||
if (sockfd = socket(AF_INET,SOCK_STREAM,0) < 0) {
|
||||
// the error code is obtained from errno
|
||||
err = errno;
|
||||
return err;
|
||||
}
|
||||
|
||||
Error Handling of Select
|
||||
++++++++++++++++++++++++
|
||||
|
||||
The error detection
|
||||
- Socket error when select has exception descriptor
|
||||
|
||||
Get the error reason code
|
||||
- If the ``select`` indicates that the socket fails, we can't get the error reason code by accessing errno, instead we should call ``getsockopt()`` to get the failure reason code. Because ``select()`` has exception descriptor, the error code will not be given to errno.
|
||||
|
||||
.. note:: ``getsockopt`` function prototype ``int getsockopt(int s, int level, int optname, void *optval, socklen_t *optlen)``. Its function is to get the current value of the option of any type, any state socket, and store the result in optval. For example, when you get the error code on a socket, you can get it by ``getsockopt(sockfd, SOL_SOCKET, SO_ERROR, &err, &optlen)``.
|
||||
|
||||
Example::
|
||||
|
||||
int err;
|
||||
|
||||
if (select(sockfd + 1, NULL, NULL, &exfds, &tval) <= 0) {
|
||||
err = errno;
|
||||
return err;
|
||||
} else {
|
||||
if (FD_ISSET(sockfd, &exfds)) {
|
||||
// select() exception set using getsockopt()
|
||||
int optlen = sizeof(int);
|
||||
getsockopt(sockfd, SOL_SOCKET, SO_ERROR, &err, &optlen);
|
||||
return err;
|
||||
}
|
||||
}
|

In your browser, enter the URL where the website located (e.g. `http://esp-home.local`). You can also enter the IP address that ESP32 obtained if your operating system currently don't have support for mDNS service.
|

|

Besides that, this example also enables the NetBIOS feature with the domain name `esp-home`. If your OS supports NetBIOS and has enabled it (e.g. Windows has native support for NetBIOS), then the URL `http://esp-home` should also work.
