Description
Ultibo Network Sockets Interface unit
This unit incorporates the socketsh.inc header from rtl-extra and adds Ultibo specific functionality. The unit can then be used in place of the sockets unit normally provided by the rtl-extra package.
Notes: All BSD functions that accept an Address or Port expect them to be in Network order. All other functions that take an Address or Port expect them to be in Host order
This unit includes the interface normally provided by the sockets unit in the FPC package rtl-extras. The rtl-extras package does not build the sockets unit for target Ultibo as this unit will always be available to provide the required functionality for any other package that uses it.
