.Net Profiler API in 64 bit windows -FunctionMapper callback API

The FunctionMapper callback API in profiler is working fine in the 32 bit

profiler.

This feature is very useful to us because it can map a functionID to a

FunctionInfo pointer so that the callback from a function enter will return a

pointer to the FunctionInfo in the m_pfunctiontable directly. It will save

time instead of doing a lookup by function id.

However, when I port our .Net profiler to 64 bit. This feature seems to be

gone.

It can only return the functionID even though we have mapped the function ID

to pointer address by using this API ProfilerCallback::FunctionMapper.

Question?

Is the feature for function mapping in 64 bit .net profiler interface not

working anymore?

Help please.
