Internal Module

The Internal/ directory contains private implementation details, glue code, and stubs that are not part of the public API.

Subdirectories

C/ and Pascal/

Private headers and source files. These contain:

• Private APIs: Functions shared between system components but not exposed to developers.
• Internal Data Structures: Structs and records used internally by managers.
• Stubs: MiniFinder.c and VirtualMemoryStub.c are located here.

Asm/

Private assembly definitions and macros.

• SysPrivateEqu.a: Private system globals.
• Emulator68kStub.a: Stub for the 68k emulator (used on PPC or for specific build configs).

Key Files

MiniFinder.c

A reconstructed stub application that serves as a placeholder for the Finder.

• Purpose: Allows the system to boot into a known state without requiring the proprietary Finder source code.
• Functionality: Initializes the Toolbox, draws a desktop pattern, and runs a basic event loop.

VirtualMemoryStub.c

A placeholder for Virtual Memory functionality.

• Purpose: Satisfies link-time dependencies for VM calls if the full VM implementation is missing or excluded.

Role in Build

The cross_compile.sh script specifically checks for and compiles files in this directory to ensure a complete link. patch_makefile.sh ensures these objects are included in the final link list.
