In such cases, a successful return can be distinguished from an error return by setting errno to zero before the call, and then, if the call returns a status that indicates Attempts to manipulate the object before the call completes return EALREADY. select(max_descriptor+1, &read_flags,&write_flags,(fd_set*)0,&wait_time); ......

You get this error when you try to transmit data over a socket, without first specifying a destination for the data. I also trying setting a loop so the function waits for data but it always received -1. Macro: int ENAMETOOLONG Filename too long (longer than PATH_MAX; see Limits for Files) or host name too long (in gethostname or sethostname; see Host Identification). Macro: int ENXIO No such device or address.

It will not work with modern versions of the C library. This is probably suboptimal - not every error code indicates that the message should be resent. For details of in-depth Linux/UNIX system programming training courses that I teach, look here. Linux Kernel Error Codes And, putting some kind of timeouts on your I/O is pretty much ALWAYS a good idea, IMHO...

Generic Operating System Services » 15.16. errno -- Standard errno system symbols¶ This module makes available standard errno system symbols. Macro: int EPROTONOSUPPORT The socket domain does not support the requested communications protocol (perhaps because the requested protocol is completely invalid).

Photoshop's color replacement tool changes to grey (instead of white) — how can I change a grey background to pure white? Error Eintr C libraries in many older Unix systems have EWOULDBLOCK as a separate error code. Eagain Definition You'll block literally forever, because the peer machine will NEVER send anything else to you, and you'll never send it anything, since you're blocked waiting to read...

You haven't actually posted enough code to suggest there is a programming fault, although can I ask if when you detect the connection is closed that you also close down your This might be a realistic solution for the timeframe of within the week :) It probably requires configuration of the syslog daemon.

C Programming Error Codes You can use select to find out when the operation will be possible; see Waiting for I/O.

I'm getting some of our C developers to take a look at this; we need to find some way around this issue by the end of the week. int theLen=1500; //3000; int ret=0; unsigned char datosRecibidos[3000]; int flags =fctl(c->fd_get, F_GETFD; if((flags & O_NONBLOCK) == O_NONBLOCK){ fprint(stderr, "yup, its nonblocking"); } else{ fprint(stderr, "nope, its blocking"); } while (c->bFin==false){ ret

If this could be possible I would like to 'listen' to UV_WRITABLE events only when needed. I think your solution and mine are very similar, just performing the retry at different levels - yours within unix-dgram, and mine within winston-syslog, using its message queuing. Is there any particular strategy to be followed 2) Is buffer size has exceeded its limits is the only reason ? 3) Can someone please give me a better idea/code, how So, you should run the recv call again.

Can 'it' be used to refer to a person? This is used to indicate various kinds of problems with passing the wrong argument to a library function.

When you get this error, you can be sure that this particular function will always fail with ENOSYS unless you install a new version of the C library or the operating On the reconnection: the http-get tunnel is set ok, i mean, the socket connects and receives a "HTTP OK", so the program sends a RTSP "DESCRIBE" but the recv always return

If you are sending UDP packets, then keep in mind that there is no guarantee of congestion control, and if you're sending packets over the Internet you will almost certainly get In non-blocking mode it would return EAGAIN in this case. If yes then after how much time should I try again. Going into a tight retry loop works, but doesn't seem a good way to approach things.

Found a bug? Making the socket blocking makes this problem disappear at the cost of some waiting: https://github.com/brikteknologier/node-unix-dgram/compare Certainly, the solution @santigimeno proposes is preferable and more in tune with node.js design, but a This indicates that the function called is not implemented at all, either in the C library itself or in the operating system. How to cope with too slow Wi-Fi at hotel?

secondly i m not sure but probably check buff size like below if is already predefined Code: getconf -a |grep SOCK_MAXBUF and set and get send/rec buff size maybe try like I haven't looked to other Unix socket implementations to know if their behaviour is the same as the Linux Thanks briktop commented Dec 2, 2013 I'm also having this problem on fork can return this error.
