  [out] PPEER_GROUP_PROPERTIES *ppProperties
);

Handle to a peer group whose properties are retrieved. This handle is returned by the PeerGroupCreate, PeerGroupOpen, or PeerGroupJoin function. This parameter is required.

[out] ppProperties

Pointer to a PEER_GROUP_PROPERTIES structure that contains information about peer group properties. This data must be freed with PeerFreeData. This parameter is required.

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

Return code	Description
E_INVALIDARG	One of the parameters is not valid.
E_OUTOFMEMORY	There is not enough memory to perform a specified operation.
PEER_E_GROUP_NOT_READY	The group is not in a state where peer group properties can be retrieved. For example, PeerGroupJoin is called, but synchronization with the group database has not completed.

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