ICorProfilerInfo4 Interface
Provides methods that code profilers use to communicate with the common language runtime (CLR) to control event monitoring and request information. . The ICorProfilerInfo4 interface is an extension of the other ICorProfilerInfo interfaces. It provides new methods to support just-in-time (JIT) recompilation, added in .NET Framework 4.5.
Methods
| Method | Description |
|---|---|
| EnumJITedFunctions2 Method | Returns an enumerator for all functions that were previously JIT-compiled and JIT-recompiled. |
| EnumThreads Method | Gets an enumerator that provides methods to sequentially iterate through the collection of all managed threads in the profiled process. |
| GetCodeInfo3 Method | Gets the extents of native code associated with the JIT-recompiled version of the specified function. |
| GetFunctionFromIP2 Method | Maps a managed code instruction pointer to the JIT-recompiled version of a specified function. |
| GetILToNativeMapping2 Method | Gets a map from common intermediate language (CIL) offsets to native offsets for the code contained in the JIT-recompiled version of the specified function . |
| GetObjectSize2 Method | Returns the size of a specified object. |
| GetReJITIDs Method | Returns an array of IDs that identify all JIT-recompiled versions of the specified function that are still allocated. |
| InitializeCurrentThread Method | Initializes the current thread in advance of subsequent profiler API calls on the same thread, so that deadlock can be avoided. |
| RequestReJIT Method | Requests a JIT recompilation of all instances of the specified functions. |
| RequestRevert Method | Reverts all instances of the specified functions to their original versions. |
Remarks
The CLR implements the methods of the ICorProfilerInfo4 interface by using the free-threaded model. Each method returns an HRESULT to indicate success or failure. For a list of possible return codes, see the CorError.h file.
