Arguments
...
| Type | Name | Comment |
| SdaiUnsignedInt | serverContextId | Context identification, from edmiDefineServerContext |
| SdaiInteger | numberOfConnections | A variable that will receive the number of thick EDMclients that are connected to the remote _EDMdatabase{_}.remote EDMdatabase |
| SdaiWhoIsOnServer | pWhoIsOn | A variable that will receive a pointer to a tEdmiWhoIsOnServer data structure. See the description of this data structure below. |
| SdaiInvocationId | edmiInvocationId | Currently not used. |
The type definition of the tEdmiWhoIsOnServer data structure is done in the sdai.h header file:
typedef struct EDMI_WHO_IS_ON_SERVER {
unsigned int numberOfConnections;
SdaiClientId myClientId;
tEdmiConnection connections[1];
} tEdmiWhoIsOnServer;
Description of the tEdmiWhoIsOnServer struct:
numberOfConnections | The number of thick EDMclients that were connected to a remote EDMdatabase at the point of time when edmiRemoteWhoIsOn function was invoked. This value will also be returned in the functions <numberOfConnections> argument. |
myClientId | The numeric clientId that identifies the connected thick EDMclient that invoked the edmiRemoteWhoIsOn operation. |
connections | A pointer to a buffer of tEdmiConnection data structures. There will be one element for each connected thick EDMclient in the remote EDMdatabase. See the description of this data stucture below. |
The type definition of the tEdmiConnection data structure is done in the sdai.h header file:
typedef struct EDMI_CONNECTION {
unsigned int clientIndex;
SdaiClientId clientId;
InstanceId groupId;
EdmiPackedDate connectionTime;
} tEdmiConnection;
Description of the tEdmiConnection struct:
clientIndex | 1 – max named users. |
clientId | A numeric clientId that identifies the connection of a thick EDMclient in the remote _EDMdatabase_ |
userId | The userId of the EDMuser account that connected to the remote _EDMdatabase._ |
groupId | The groupId of the EDMgroup account that was used by the EDMuser when connecting to the remote _EDMdatabase._ |
connectionTime | The date and point of time at which the EDMuser connected to the actual EDMserver. |
