HS Sockets is a C source code library for interfacing to network socket layer. HS Sockets runs on Windows desktop OS (XP,Vista,7), Windows Mobile OS and on Linux OS. HS Sockets is supplied with full C source code and binaries for these platforms

HS Sockets optionally supports secure network sockets using OpenSSL library

HS Sockets hides the complexity of low level socket api from user application, enabling the programmer to considerably reduce development time.

HS Sockets operates in an asynchronous, non-blocking mode and support multiple TCP client and server connections and UDP sessions concurrently

The use of HS Sockets C Source Library is Royalty Free.

Features:
* TCP and UDP sessions
* Supports multiple sessions operating concurently
* Supports multiple client and multiple server sessions concurrently
