BTI_SINT PvGetMkdeClientHandlesData(

BTI_LONG hConnection,

PVCLIENTID* pClientId,

BTI_ULONG_PTR pCount);


In	hConnection	Connection handle that identifies the server. Connection handles are obtained with the PvConnectServer() function.
In	pClientId	Address of the PVCLIENTID structure to identify the MKDE client.
Out	pCount	Address of an unsigned long to receive the number of handles for the MKDE client.


P_OK	The operation was successful.
P_E_INVALID_HANDLE	Invalid connection handle.
P_E_DATA_UNAVAILABLE	Data related to MKDE clients not available.
P_E_NULL_PTR	Call with NULL pointer.
P_E_FAIL	Failed for other reasons.

When you call this function, all information regarding MKDE client handles is cached by DTI for subsequent function calls related to MKDE client handles. If you want to obtain other information about MKDE clients, see PvGetMkdeClientsData().

This function should be called first before calling any other functions that return MKDE client handle information.

The cached information for the MKDE client handles will be freed along with the information about the MKDE clients when PvFreeMkdeClientsData() is called.

The following preconditions must be met:

•

Connection established by PvConnectServer() or if you are performing the operation on a local machine, P_LOCAL_DB_CONNECTION may be used as the connection handle.

•

Data for active clients retrieved by calling PvGetMkdeClientsData().

•

Caller already has a valid active MKDE client ID.
