CcGetFileObjectFromSectionPtrs function (ntifs.h)
Given a pointer to the section object pointers for a cached file, the CcGetFileObjectFromSectionPtrs routine returns a pointer to the file object that the cache manager is using for the file.
Syntax
PFILE_OBJECT CcGetFileObjectFromSectionPtrs(
[in] PSECTION_OBJECT_POINTERS SectionObjectPointer
);
Parameters
[in] SectionObjectPointer
Pointer to a structure containing the file object's section object pointers.
Return value
A pointer to the file object, or NULL if the file is not cached or is no longer cached.
Remarks
The file system is responsible for ensuring that the file object remains valid while in use. It is impossible for the cache manager to guarantee this.
By using CcGetFileObjectFromSectionPtrs, you lose some caching functionality. Instead, use the CcGetFileObjectFromSectionPtrsRef routine, which provides the same functionality as CcGetFileObjectFromSectionPtrs as well as creating a reference for the object.
