Socket Error Codes Unix


Out-of-band data may also be transmitted as described in send(2) and received as described in recv(2). connectSocket = socket(AF_INET, SOCK_STREAM, 0); if (connectSocket < 0) { if (errno == EACCESS) ... For example, if you try to delete a file that is the root of a currently mounted filesystem, you get this error. If a piece of data for which the peer protocol has buffer space cannot be successfully transmitted within a reasonable length of time, then the connection is considered to be dead. weblink

When a session has been completed a close(2) may be performed. Macro: int ENOENT No such file or directory. So in Winsock applications the WSAEWOULDBLOCK error code would be returned, while in UNIX applications the EWOULDBLOCK error code would be returned. Macro: int EDEADLK Deadlock avoided; allocating a system resource would have resulted in a deadlock situation. check here

Linux Socket Error Codes

Macro: int EAFNOSUPPORT The address family specified for a socket is not supported; it is inconsistent with the protocol being used on the socket. for example for the "getaddrinfo" function i can do this: //Resolve the server address and port result = (struct addrinfo *) calloc(1, sizeof(struct addrinfo)); iResult = getaddrinfo("google.com", DEFAULT_PORT, &hints, &result); if Macro: int ERANGE Range error; used by mathematical functions when the result value is not representable because of overflow or underflow. For details of in-depth Linux/UNIX system programming training courses that I teach, look here.

What is the meaning of card in the sentence "I'm a wild card."? Macro: int EFTYPE Inappropriate file type or format. See Socket Addresses. Linux Errno To String Macro: int EGRATUITOUS This error code has no purpose.

Macro: int EHOSTUNREACH The remote host for a requested network connection is not reachable.

Posix Error Codes

A stream socket must be in a connected state before any data may be sent or received on it. http://stackoverflow.com/questions/27096985/getting-error-code-when-creating-a-socket-in-linux This error never occurs on GNU/Hurd systems. Linux Socket Error Codes These defines remain commented out in the Winsock2.h header within an #ifdef 0 and #endif block. Linux Errno Example SOCK_PACKET is an obsolete socket type to receive raw packets directly from the device driver.

Macro: int EDOM Domain error; used by mathematical functions when an argument value does not fall into the domain over which the function is defined. have a peek at these guys Macro: int ETOOMANYREFS ??? Errors: Linux System Errors When system requests fail, error code are returned. Macro: int ENOTDIR A file that isn’t a directory was specified when a directory is required. Enotsup

Macro: int ESOCKTNOSUPPORT The socket type is not supported. This documentation is archived and is not being maintained. Macro: int ENOMEM No memory available. check over here The protocol specifies a particular protocol to be used with the socket.

If an application developer insists on using the BSD error codes for compatibility, then an application may choose to include a line of the form: C++ Copy #include #define errno

Macro: int EINPROGRESS An operation that cannot complete immediately was initiated on an object that has non-blocking mode selected. Macro: int ENETRESET A network connection was reset because the remote host crashed. Not satisfied Very satisfied What can we do to improve your experience? Einval Errno You can use perror in stdio.h to print an error message based on the value of errno or you can use strerror in string.h to access a string describing the error

On GNU/Hurd systems, this error can happen for many calls when the object does not support the particular operation; it is a generic indication that the server knows nothing to do This error is never generated by GNU/Hurd systems, but it can result from an operation to an NFS server running another operating system. Also, the BSD socket errors are defined to very different values than are used in UNIX, BSD, and Linux programs. this content The host refused service for some reason.

Macro: int ECONNRESET A network connection was closed for reasons outside the control of the local host, such as by the remote machine rebooting or an unrecoverable protocol violation. Macro: int ENOEXEC Invalid executable file format. Hosting by jambit GmbH. Macro: int EHOSTDOWN The remote host for a requested network connection is down.

This condition is detected by the exec functions; see Executing a File. In GNU, this error is always synonymous with ENOMEM; you may get one or the other from network operations. It indicates that the shortage is expected to pass, so your program can try the call again later and it may succeed. Yes No Yes No Thank you for your feedback. 0 Comments Please log in to post comments.

The man page for many library functions will indicate that they return -1 on error, and set errno. Macro: int ECONNABORTED A network connection was aborted locally. The communications protocols which implement a SOCK_STREAM ensure that data is not lost or duplicated. You get this error when you try to transmit data over a connectionless socket, without first specifying a destination for the data with connect.

For example, trying to mount an ordinary file as a file system in Unix gives this error. Macro: int EAGAIN Resource temporarily unavailable; the call might work if you try again later. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! ENOENT No such file or directory Connection could not be established.

Macro: int ED The experienced user will know what is wrong. A function returns this error when certain parameter values are valid, but the functionality they request is not available.
