PolFreeHeader callback function

A Policy DLL's PolFreeHeader callback function is called to enable the Policy DLL to return the storage that it previously allocated for Policy DLL Header Data.

Syntax

VOID
PolFreeHeader(

    _In_  PVOID PolHeaderData,

    _In_  DWORD PolHeaderDataSize

)

Parameters

PolHeaderData [in]

A pointer to a Header Data area to be returned that was previously allocated by the Policy DLL.

PolHeaderDataSize [in]

The size, in bytes, of the Header Data area.

Return value

Remarks

A Policy DLL's PolFreeHeader callback function is called by FESF to allow the Policy DLL to deallocate space that it previously allocated for storage of Policy DLL Header Data.  This Header Data was provided to FESF by the Policy DLL on return from the PolGetKeyNewFile callback function.

Policy DLLs must implement this callback function.
