Routine Description:
|
||
|
||
This routine calls a common bind routine that is shared by all services.
|
||
This routine is called from the schedule service client stubs when
|
||
it is necessary to bind to a server.
|
||
|
||
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 bind is
|
||
unsuccessful, a NULL will be returned.
