3. Agenda What are shared object files?
Early vs Late binding to shared object files (.so)
Create and consume a shared object library
Finding headers and documentation
Header translation (basics)
The X-Server
Creating an X-Server application

4. Shared Object Files
Comparable to .DLL (Dynamic Link Libraries) from Windows systems.
.so File extension
Elf format files with a number of ‘Exports’
Typically the ‘cdecl’ calling convention.
Provide the ‘API’ for Linux
Common (minor differences) across multiple *nix platforms.

5. Early vs Late binding Not to be confused with static binding.
Early binding requires interaction from the linker.
Late binding involves calling the API for function pointers.
Function pointer types must be defined.
Early binding issue in Delphi?
Header File import.

6. Shared Object Files
Lets create and consume our own shared object file.
