NN_CONNECT(3)                   nanomsg manual                   NN_CONNECT(3)


NAME

       nn_connect - add a remote endpoint to the socket


SYNOPSIS

       #include <nanomsg/nn.h>

       int nn_connect (int s, const char *addr);


DESCRIPTION

       Adds a remote endpoint to the socket s. The library would then try to
       connect to the specified remote endpoint.

       The addr argument consists of two parts as follows:
       transport://address. The transport specifies the underlying transport
       protocol to use. The meaning of the address part is specific to the
       underlying transport protocol.

       For the list of available transport protocols check the list on
       nanomsg(7) manual page.

       Maximum length of the addr parameter is specified by NN_SOCKADDR_MAX
       defined in <nanomsg/nn.h> header file.

       Note that nn_connect and nn_bind(3) may be called multiple times on the
       same socket thus allowing the socket to communicate with multiple
       heterogeneous endpoints.


RETURN VALUE

       If the function succeeds positive endpoint ID is returned. Endpoint ID
       can be later used to remove the endpoint from the socket via
       nn_shutdown(3) function.

       If the function fails negative value is returned and errno is set to to
       one of the values defined below.


ERRORS

       EBADF
           The provided socket is invalid.

       EMFILE
           Maximum number of active endpoints was reached.

       EINVAL
           The syntax of the supplied address is invalid.

       ENAMETOOLONG
           The supplied address is too long.

       EPROTONOSUPPORT
           The requested transport protocol is not supported.

       ENODEV
           Address specifies a nonexistent interface.

       ETERM
           The library is terminating.


EXAMPLE

           s = nn_socket (AF_SP, NN_PUB);
           eid1 = nn_connect (s, "ipc:///tmp/test.ipc");
           eid2 = nn_connect (s, "tcp://server001:5560");
