;
|

|
|
; This module is dependent on the internal structure of the
|
|||
|
|
; COleStaticMutexSem object (g_Rpcrt4Sem). It invokes the
|
|||
|
|
; COleCommonMutexSem::Request method, as well as invokes
|
|||
|
|
; COleStaticMutexSem::ReleaseFn. Any changes to this object
|
|||
|
|
; may impact this code -- BEWARE!
