81 Signals this thread that an asynchronous request originating from this thread,
84 The request is associated with the specified request status object supplied
87 Typically, the caller of this function is the service provider responsible
88 for satisfying the request made by this thread.
90 The request is completed with the completion code passed in aReason. This
91 value is copied into this thread's request status, *aStatus, before signalling
92 this thread's request semaphore.
94 The meaning of the completion code is a matter of convention to be decided
95 between the service provider and this thread.
97 In a client-server situation, completion of a request takes place in the context
98 of the server thread, but the pointer is interpreted in the address space
101 It is often the case in client-server situations that the client and the server
102 are in the same address space (i.e. the same process).
104 Setting the pointer to the request status to NULL is a convenience, not all
107 @param aStatus A reference to a pointer to the request status originally
108 supplied by this thread. This is a pointer into this thread's
109 address space, which may be different to the thread currently
110 executing (this code). On return, the pointer to the request
111 status is set to NULL.
113 @param aReason The completion code of this request.
