ISimilarityFileIdTable::CreateTable method (msrdc.h)

  • Article

Creates or opens a similarity file ID table.

Syntax

HRESULT CreateTable(
  [in]  wchar_t          *path,
  [in]  BOOL             truncate,
  [in]  BYTE             *securityDescriptor,
  [in]  DWORD            recordSize,
  [out] RdcCreatedTables *isNew
);

Parameters

[in] path

A pointer to a null-terminated string that specifies the name of the file that will contain the similarity file ID table. The alternate stream name ":FileId" will be appended to the end of this file name. For more information, see Naming a File.

[in] truncate

TRUE if a new similarity file ID table should always be created or truncated. If FALSE is specified and the table exists and is valid, it may be used; otherwise, if the table is not valid or does not exist, the existing table is overwritten.

[in] securityDescriptor

A pointer to a security descriptor to use when opening the file. If this parameter is NULL, the file is assigned a default security descriptor. The access control lists (ACL) in the file's default security descriptor are inherited from the file's parent directory. For more information, see the lpSecurityAttributes parameter of the CreateFile function.

[in] recordSize

The size, in bytes, of the file IDs that will be stored in the similarity file ID table. All file IDs must be the same size. The valid range is from SimilarityFileIdMinSize to SimilarityFileIdMaxSize. If an existing similarity file ID table is being opened, the value of this parameter must match the file ID size of the existing table. Otherwise, the existing table is assumed to be not valid and will be overwritten.

[out] isNew

A pointer to a variable that receives an RdcCreatedTables enumeration value that describes the state of the similarity file ID table. If a new table is created, this variable receives RDCTABLE_New. If an existing table is used, this variable receives RDCTABLE_Existing. If this method fails, this variable receives RDCTABLE_InvalidOrUnknown.

Return value

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

Remarks

If an existing table is being opened, the table must be valid, and the value of the recordSize parameter must match the record size of the existing table. Otherwise, the existing table is overwritten, even if FALSE is specified for the truncate parameter.
