IRdcLibrary::CreateComparator method (msrdc.h)

  • Article

The CreateComparator method creates a signature comparator.

Syntax

HRESULT CreateComparator(
  [in]  IRdcFileReader *iSeedSignaturesFile,
  [in]  ULONG          comparatorBufferSize,
  [out] IRdcComparator **iComparator
);

Parameters

[in] iSeedSignaturesFile

An IRdcFileReader interface pointer initialized to read the seed signatures.

[in] comparatorBufferSize

Specifies the size of the comparator buffer. The range is from MSRDC_MINIMUM_COMPAREBUFFER to MSRDC_MAXIMUM_COMPAREBUFFER.

MSRDC_MINIMUM_COMPAREBUFFER (100000)

Minimum size of a comparator buffer.

MSRDC_DEFAULT_COMPAREBUFFER (3200000)

Default size of a comparator buffer. Used if zero (0) is passed for comparatorBufferSize.

MSRDC_MAXIMUM_COMPAREBUFFER (1073741824)

Maximum size of a comparator buffer. (1<<30)

[out] iComparator

Pointer to a location that will receive an IRdcComparator interface pointer. On a successful return the interface will be initialized on return. Callers must release the interface.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The caller must create a separate signature comparator for each level of recursion.
