+EVENTLOG_HANDLE_W_bind (

+
+Routine Description:
+    This routine calls a common bind routine that is shared by all services.
+    This routine is called from the ElfOpenEventLog API client stub when
+    it is necessary to bind to a server.
+    The binding is done to allow impersonation by the server since that is
+    necessary for the API calls.
+
+Arguments:
+
+    ServerName - A pointer to a string containing the name of the server
+        to bind with.
+
+Return Value:
+
+    The binding handle is returned to the stub routine.  If the
+    binding is unsuccessful, a NULL will be returned.
