• New API:
  • Exported function signature introspection: m3_GetArgCount, m3_GetRetCount, m3_GetArgType, m3_GetRetType
  • Introspection of imported functions (see IM3ImportContext _ctx argument)
  • Calls with raw arguments, instead of strings: m3_CallV, m3_CallVL, m3_Call
  • Warning: m3_CallWithArgs renamed to m3_CallArgv
  • Get return values: m3_GetResultsV, m3_GetResultsVL, m3_GetResults
  • Get backtrace: m3_GetBacktrace
