Your system may also allow you to use the MSG_NOSIGNAL option in the recv to avoid the raise of the SIGPIPE signal : recv(fd, odp, 100, MSG_NOSIGNAL )) I think it share|improve this answer answered Aug 19 at 15:26 oratofu 112 Thank you for valuable info about colors - but you know that article is about connection right? :-) –Bruno MSG_PEEK This flag causes the receive operation to return data from the beginning of the receive queue without removing that data from the queue.

It is normally used with connected sockets because it does not permit the application to retrieve the source address of received data. Also, the following call recv(sockfd, buf, len, flags); is equivalent to recvfrom(sockfd, buf, len, flags, NULL, NULL); All three calls return the length of the message on successful completion. recv() The recv() call is normally used only on a connected socket (see connect(2)). len [in] The length, in bytes, of the buffer pointed to by the buf parameter.

MSG_CTRUNC indicates that some control data were discarded due to lack of space in the buffer for ancillary data. I'm getting the following error can someone please help me how to get out of it..

The point is, all the information is as you sent it, just broken up into different sized packets (specifically, NOT the ones you sent). > How to solve it? The user should supply a buffer of sufficient size.

The returned address is truncated if the buffer provided is too small; in this case, addrlen will return a value greater than was supplied to the call. If no messages are available at the socket, the receive calls wait for a message to arrive, unless the socket is nonblocking (see fcntl(2)), in which case the value -1 is

See the Remarks section for details on the possible value for this parameter. It is equivalent to the call: recvfrom(fd, buf, len, flags, NULL, 0); recvmsg() The recvmsg() call uses a msghdr structure to minimize the number of directly supplied arguments.
