If you really want to force a block until the recv() is somewhat successful, you may wish to use the MSG_WAITALL flag. You can use the select function to find out when the pending operation has completed; see Waiting for I/O.

Some of these are marked POSIX.1, indicating that the name is defined by POSIX.1-2001, or C99, indicating that the name is defined by C99. 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 A function returns this error when certain parameter values are valid, but the functionality they request is not available. Errno.h Linux Kernel If the value of errno should be preserved across a library call, it must be saved: if (somecall() == -1) { int errsv = errno; printf("somecall() failed\n"); if (errsv == ...)

Macro: int ENETUNREACH A socket operation failed because the subnet containing the remote host was unreachable.

This can mean that the device file was installed incorrectly, or that the physical device is missing or not correctly attached to the computer.

You get this error when you try to transmit data over a socket, without first specifying a destination for the data. C Programming Error Codes For a connectionless socket (for datagram protocols, such as UDP), you get EDESTADDRREQ instead.

Valid error numbers are all nonzero; errno is never set to zero by any system call or library function. fork can return this error.
