• ✅ Structs with nested fields
• ✅ Enums with values
• ✅ Unions
• ✅ Flags (enum-based bitfields)
• ✅ Typedefs
• ✅ Function pointers

Parsing Capabilities

• ✅ Function declarations with complex signatures
• ✅ Multi-line declarations
• ✅ Array parameters
• ✅ Variadic functions
• ✅ Const/volatile qualifiers
• ✅ Pointer-to-pointer types
• ✅ Anonymous unions/structs (in progress)

Dependency Resolution

• ✅ Automatic include scanning
• ✅ Cross-header type resolution
• ✅ Typedef scanning for dependencies
• ✅ Recursive dependency tracking

Output Formats

• ✅ Zig code generation
• ✅ Mock implementations
• ✅ JSON export (prettified)

Known Limitations

1. Macros: Not parsed (SDL_COMPILE_TIME_ASSERT, etc.)
2. Inline functions: Not extracted from headers
3. Bit fields: Struct bit fields not supported
4. Complex macros: Function-like macros ignored

Next Steps

1. Test Zig bindings compilation
2. Add platform-specific headers (SDL_metal.h, SDL_egl.h)
3. Generate complete API documentation
4. Create integration tests
