See Connecting. To understand the nature of the error these codes need to be interpreted.
Some socket functions don’t make sense for all types of sockets, and others may not be implemented for all communications protocols. Macro: int ECHILD There are no child processes. I have the following code inside a loop, but the recvfrom never times out. Errno 0 Macro: int EPROCUNAVAIL ???

Macro: int EINPROGRESS An operation that cannot complete immediately was initiated on an object that has non-blocking mode selected.
Such shortages are usually fairly serious and affect the whole system, so usually an interactive program should report the error to the user and return to its command loop. For a connectionless socket (for datagram protocols, such as UDP), you get EDESTADDRREQ instead. Linux Errno Values Why does Mal change his mind?

Macro: int EPIPE Broken pipe; there is no process reading from the other end of a pipe.

Macro: int ENOTDIR A file that isn’t a directory was specified when a directory is required. This condition is detected by the exec functions; see Executing a File. Macro: int EPROTOTYPE The socket type does not support the requested communications protocol. Errno To String Macro: int ENOSYS Function not implemented.
Macro: int ERANGE Range error; used by mathematical functions when the result value is not representable because of overflow or underflow. Macro: int EGREGIOUS You did what? For example, "Error no is : 17", which doesn't really say much. useful reference Macro: int ENOTSUP Not supported.
A temporary resource shortage made an operation impossible. All of them expand into integer constant values. Macro: int ENOTTY Inappropriate I/O control operation, such as trying to set terminal modes on an ordinary file. See Socket Addresses.

Macro: int ESHUTDOWN The socket has already been shut down. The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library.
If the entire function is not available at all in the implementation, it returns ENOSYS instead. Why aren't there direct flights connecting Honolulu, Hawaii and London, UK? Trying the same operation again will block until some external condition makes it possible to read, write, or connect (whatever the operation). Its value is significant only when the return value of the call indicated an error (i.e., -1 from most system calls; -1 or NULL from most library functions); a function that
