_CorValidateImage Function

Notifies the loader when the managed module images are loaded.

In Windows XP, the operating system loader checks for managed modules by examining a bit in the common object file format (COFF) header. A set bit denotes a managed module. If the loader detects managed modules, it loads Mscoree.dll. _CorValidateImage notifies the loader when the managed module images are loaded, and _CorImageUnloading notifies the loader when the managed module images are unloaded. _CorValidateImage performs the following actions:

  • Ensures that the code is valid managed code.

  • Changes the entry point in the image to an entry point in the runtime.

For 64-bit versions of Windows, _CorValidateImage modifies the image that is in memory by transforming it from PE32 to PE32+ format.

STDAPI _CorValidateImage ( 
     [in] PVOID* ImageBase,
     [in] LPCWSTR FileName
);

Parameters
