Translating C headers

 



A FreeBASIC header should expose the C library interface accurately while still
looking like normal FreeBASIC source. Start from the C declarations, translate
types and calling conventions carefully, then keep platform-specific differences
visible instead of hiding them behind guesses.

Basic process

• Identify the library version and platform ABI being translated.
  
• Translate constants, enums, structs, unions, callbacks, and functions.
  
• Use the C type comparison table for integer, pointer, string, and size
  

• Keep conditional declarations close to the platform condition that requires
  

• Compile small examples against the header on the target platform.
