PeerGroupImportDatabase function

-description

The PeerGroupImportDatabase function imports a peer group database from a local file.

-parameters

-param hGroup [in]

Handle to a peer group whose database is imported from a local file. This handle is returned by the PeerGroupCreate, PeerGroupOpen, or PeerGroupJoin function. This parameter is required.

-param pwzFilePath [in]

Pointer to a Unicode string that contains the absolute file system path and file name where the data is stored, for example, "C:\backup\p2pdb.db". If the file does not exist at this location, an appropriate error from the file system is returned. This parameter is required.

-returns

Returns S_OK if the operation succeeds. Otherwise, the function returns one of the following values.

Note  If an import fails due to a file system error, the appropriate file system error is returned.

 

Return code	Description
E_INVALIDARG	One of the parameters is not valid.
PEER_E_GROUP_IN_USE	The operation cannot be completed because the peer group database is currently in use. For example, PeerGroupConnect has been called by a peer, but has not yet completed any database transactions.
PEER_E_INVALID_GROUP	The handle to the peer group is invalid.

 

Cryptography-specific errors can be returned from the Microsoft RSA Base Provider. These errors are prefixed with CRYPT_* and defined in Winerror.h.

-remarks

This function must be called before PeerGroupConnect, and after PeerGroupOpen or PeerGroupJoin.
