- Fixed parseStructField to correctly extract field names from function pointer declarations
- Pattern: RetType (SDLCALL *field_name)(params) now correctly identifies 'field_name'
- Prevents function pointer types from causing recursion in convertType
- Function pointer types temporarily converted to ?*const anyopaque placeholder
- SDL_IOStreamInterface now parses correctly with proper field names (size, seek, read, write, flush, close)
- Next step: implement full function pointer type conversion to Zig syntax
