   PVOID Buffer,
   PSZ   FileName,
   ULONG LineNumber
);

Remarks

It is recommended that the RxFreePool macro be called instead of using this routine directly. On retail builds, this macro is defined to call ExFreePool.

Memory allocated with _RxAllocatePoolWithTag should be released by calling _RxFreePool.

The _RxFreePool routine calls ExFreePool.
