In eclipse, you can highlight a call to some C/C++ function, right click and do "Open Call Hierarchy".
This shows more information than the "References" window in SE. It shows all the chains of function calling that led to the function you are searching for.
The eclipse "Open Call Hierarchy" not only shows which functions are calling your functions (SE references window only shows the caller), but it shows the "grandfather", and other ancestors on the call tree.
It would be very useful to have this in SE.
For example, lets say we have this situation in the code:
funcA() calls funcB()
funcB() calls funcC()
funcD() calls funcE()
funcE() calls funcC()
Then if I do "Open Call Hierarchy" in eclipse on funcC(), I see a tree like structure as follows:
funcC
funcB
funcA
funcC
funcE
funcD
So I can see down the whole chain the hierarchy of function calls that could lead to funcC() getting called.
I can also click anywhere in the hierarchy to find the line of code where the call is happening in the grandfather/great-grandfather function, etc.
I don't see this same functionality in SE, and I think it could be very useful to add it if it is not already there.
If this is already in SE, please let me know how to find it.
