+* @name NtfsDumpFileRecord

+*
+* Provides diagnostic information about a file record. Prints a hex dump
+* of the entire record (based on the size reported by FileRecord->ByesInUse),
+* then prints a dump of each attribute.
+*
+* @param Vcb
+* Pointer to a DEVICE_EXTENSION describing the volume.
+*
+* @param FileRecord
+* Pointer to the file record to be analyzed.
+*
+* @remarks
+* FileRecord must be a complete file record at least FileRecord->BytesAllocated
+* in size, and not just the header.
