Summary

Member Variables

Name	Description
const intptr_t * externalReferences	Optional. A raw address array with a nullptr at the end in the embedder, which can be matched by the VM during serialization and can be used for deserialization. This array and its contents must remain valid throughout the lifecycle of the VM instance.
int * argc	VM flag. If removeFlags is true, the identified flags are removed from (argc, argv). Note that these flags are now only available to V8 VMs. They are mainly used for development. Do not use them in the production environment because they may not take effect if the VM is different from the development environment.
char ** argv	argv.
bool removeFlags	Whether to remove flags.
