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.
