[Mono-dev] how-to-protect-object-created-by-mono-object-new-from-gc

It shouldn't be, because there will be a reference on the native stack or machine registers between step1 and step2 and those areas will be scanned by the garbage collector.

hi,all:

I embed the mono in my game engine.And create managed object by invoke mono_object_new then call mono_gchandle_new to ref the object.

step1:

MonoObject* monoObject= mono_object_new()

step2

uint32_t objectHandle = mono_gchandle_new(monoObject,false);

Will monoObject be gabage collected between step1 and step2? If yes how to prevent it.


Thanks.
