erlang gen_tcp

Erlang gen_tcp is a module that provides a TCP/IP socket interface for communicating with remote hosts over a network. It is used to create and manage TCP/IP sockets for both client and server applications.

The gen_tcp module provides a set of functions for creating and manipulating TCP/IP connections, such as:

• gen_tcp:listen/2 - creates a listening socket for incoming connections
• gen_tcp:connect/3 - establishes a connection to a remote host
• gen_tcp:send/2 - sends data over a TCP/IP connection
• gen_tcp:recv/2 - receives data from a TCP/IP connection

In addition to these basic functions, gen_tcp also provides additional features such as support for SSL/TLS encryption, non-blocking I/O operations, and the ability to set various socket options.

Erlang gen_tcp is widely used in distributed systems and network programming, as it provides a simple and efficient way to communicate with other systems over a network.
