ClfsAlignReservedLog function

Description

The ClfsAlignReservedLog routine calculates the size of the space that must be reserved for a specified set of records. The size calculation includes the space required for headers and the space required for sector alignment.

Parameters

pvMarshalContext [in]

A pointer to an opaque context that represents a marshalling area associated with a CLFS stream. The caller previously obtained this pointer by calling ClfsCreateMarshallingArea.

cRecords [in]

The number of elements in the array pointed to by rgcbReservation.

rgcbReservation [in]

A pointer to an array of LONGLONG-typed variables that supplies a list of record sizes (in bytes).

pcbAlignReservation [out]

A pointer to a LONGLONG-typed variable that receives the size, in bytes, of the required reservation.

Return value

ClfsAlignReservedLog returns STATUS_SUCCESS if it succeeds; otherwise, it returns one of the error codes defined in Ntstatus.h.

Remarks

For an explanation of CLFS concepts and terminology, see Common Log File System.
