NN_CONNECT(3) nanomsg manual NN_CONNECT(3)NAMEnn_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");
