- ✅ Typedefs
- ✅ Function pointers

### Parsing Capabilities
- ✅ Function declarations with complex signatures
- ✅ Multi-line declarations
- ✅ Array parameters
- ✅ Variadic functions
- ✅ Const/volatile qualifiers
- ✅ Pointer-to-pointer types

### Dependency Resolution
- ✅ Automatic include scanning
- ✅ Cross-header type resolution
- ✅ Typedef scanning for dependencies
- ✅ Recursive dependency tracking

### Output Formats

## 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
