NN_TCP(7) nanomsg 1.1.5 NN_TCP(7) NAME nn_tcp - TCP transport mechanism SYNOPSIS #include <nanomsg/nn.h> #include <nanomsg/tcp.h> DESCRIPTION TCP transport allows for passing messages over the network using simple re- liable one-to-one connections. TCP is the most widely used transport proto- col, it is virtually ubiquitous and thus the transport of choice for commu- nication over the network. When binding a TCP socket address of the form tcp://interface:port should be used. Port is the TCP port number to use. Interface is one of the fol- lowing (optionally placed within square brackets): * Asterisk character (*) meaning all local network interfaces. * IPv4 address of a local network interface in numeric form (192.168.0.111). * IPv6 address of a local network interface in numeric form (::1). When connecting a TCP socket address of the form tcp://interface;ad- dress:port should be used. Port is the TCP port number to use. Interface is optional and specifies which local network interface to use. If not speci- fied, OS will select an appropriate interface itself. If specified it can be one of the following (optionally placed within square brackets): * IPv4 address of a local network interface in numeric form (192.168.0.111). * IPv6 address of a local network interface in numeric form (::1). Finally, address specifies the remote address to connect to. It can be one of the following (optionally placed within square brackets): * IPv4 address of a remote network interface in numeric form (192.168.0.111). * IPv6 address of a remote network interface in numeric form (::1). * The DNS name of the remote box. Socket Options NN_TCP_NODELAY This option, when set to 1, disables Nagle's algorithm. It also dis- ables delaying of TCP acknowledgments. Using this option improves la- tency at the expense of throughput. Type of this option is int. Default value is 0.
