HS NTP C Source Library

HS NTP is a highly functional and useful software library written in C. With its comprehensive source code, it enables seamless implementation of the Network Time Protocol (NTP) over the UDP socket layer. HS NTP supports RFC1769 and RFC1305, allowing for complete client-side synchronization to remote NTP server time. The library is available for multiple platforms, including Windows, Linux, MAC OS X, iPhone iOS, and WinCE.

This software offers a range of features, including the ability for user applications to synchronize local system time with remote NTP server time. Once initialized, the user application calls HS NTP's HsNtpGetTime, which enables a time difference calculation between the local system and remote NTP server. A user may specify the NTP server name or IP address and source UDP port to use. HS NTP library then proceeds to resolve the server name, formats, and sends an NTP time request packet, following RFC1305 and RFC1769 standard.

Once the library receives an NTP time reply from the NTP server, it analyzes and reports the resulting time difference to the user application via callback function. The event callback parameters contain the offset value in seconds, which the local clock applies to synchronize with remote NTP server time.

With a modular design, HS NTP is easily portable to any environment, allowing for quick implementation. The library interfaces with HS Sock library internally, enabling seamless UDP transport services without the need for the user application to worry about Winsock's transmission, reception, and event handling over the socket layer.

All in all, HS NTP is an excellent software tool for creating clients requiring synchronization to remote NTP servers. Its comprehensive features, cross-platform compatibility and modular design make it an excellent choice for any user application.
