It shows a lightweight example of how to program an event-driven IP socket client and server, both blended together in one GUI program (use the "Host" button to switch between server and client mode). A very good place to start exploring is the tcpudp demo contained in the. Otherwise, and for access to the latest version as well as to documentations and sample code files, see the component GIT repository hosted on GitHub. If you are using the Lazarus IDE, you can install the latest version via the Online Package Manager (OPM). The next advanced library, and the most basic one providing GUI support, is lNet (note: the first letter is a lowercase l, for "lightweight"). All samples are command-line only, and should work on all platforms which provide a socket-style networking interface. Amongst others there are basic TCP socket server and client implementations, and a DNS resolver. \fpc\.\source\packages\fcl-net\examples subdirectory of your local Lazarus installation. Code samples, which also serve as documentation, can be found in the.
It is included in the default installation.
#FREE PASCAL NET FOR FREE#
Have a look at the Brook for Free Pascal or fpctwit frameworks for examples on how to build frameworks that can use multiple network libraries Basic IP socket programming and a bit moreįor very basic applications and first steps exploring TCP socket communication the fcl-net library may be the best approach. Therefore you may see the same examples multiple times - for different libraries. Note: Because there are multiple libraries (Synapse, lnet, fphttpclient, Indy.) that provide networking functionality for FPC/Lazarus, many examples can be written for multiple libraries.
