Given a module ID, returns the file name of the module and the ID of the module's parent assembly.
HRESULT GetModuleInfo( [in] ModuleID moduleId, [out] LPCBYTE *ppBaseLoadAddress, [in] ULONG cchName, [out] ULONG *pcchName, [out, size_is(cchName), length_is(*pcchName)] WCHAR szName , [out] AssemblyID *pAssemblyId);
For dynamic modules, the szName parameter is an empty string, and the base address is 0 (zero).
Although the GetModuleInfo method may be called as soon as the module's ID exists, the ID of the parent assembly will not be available until the profiler receives the ICorProfilerCallback::ModuleAttachedToAssembly callback.
When GetModuleInfo returns, you must verify that the szName buffer was large enough to contain the full file name of the module. To do this, compare the value that pcchName points to with the value of the cchName parameter. If pcchName points to a value that is larger than cchName, allocate a larger szName buffer, update cchName with the new, larger size, and call GetModuleInfo again.
Alternatively, you can first call GetModuleInfo with a zero-length szName buffer to obtain the correct buffer size. You can then set the buffer size to the value returned in pcchName and call GetModuleInfo again.
For more information about these two approaches, see Caller-Allocated Buffers.
