Our general approach is to deprecate an API entry for 1 stable version, giving embedders time to adapt, and remove it after that. In the case at hand, GetPointerFromInternalField was deprecated in 3.15 and removed in 3.16. If there is a more or less mechanical way to replace a deprecated API entry, this will be noted in v8.h, e.g.: /** * Gets a native pointer from an internal field. Deprecated. If the pointer is * always 2-byte-aligned, use GetAlignedPointerFromInternalField instead, * otherwise use a combination of GetInternalField, External::Cast and * External::Value. */ V8EXPORT V8_DEPRECATED(void* GetPointerFromInternalField(int index)); In general, v8.h is the most up-to-date form of "API documentation". The web pages/tutorials might be out of sync and will get an overhaul at some later point in time. > I've seen the 'aligned' version of this function, > GetAlignedPointerInInternalFie**ld.

If you are unsure, use the slow route as described in the comment. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
