MProviderNotify Class Reference
|
class MProviderNotify : public MInetBase
|
Receiver of the notifications of the status changes in the flow.
Note that the two functions
CanSend()
and
Error()
are a subset of
MSocketNotify
. This allows a Service Access Point to implement the interface just by calling the equivalent
MSocketNotify
functions.

Flags that the flow might be ready to change into the EFlow_READY status
The flow is (or has been) in EFlow_PENDING or EFlow_HOLD state. The flow owner can now check if flow really can be changed into EFlow_READY state. The state is updated by calling
RFlowContext::Status
(or some other functions that implicitly refresh the flow state by calling internally the
CFlowContext::RefreshFlow
function).
Even if this function is called, the flow can still be in error or blocked state. This is because, for example, when congestion clears, all flows waiting for that event are notified, but some earlier notified flow may already have refilled all the buffers.

The flow has entered an error state.
Error state in a flow is permanent and requires a new connect (
CFlowContext::Connect
) to be cleared. A new connect occurs implicitly at FlowContext::Status (or some at some other functions), if flows connection parameters have been modified since the last connect (
CFlowContext::iChanged
is 1).
Parameters

TInt
aError
|
Flow error code
|
|
TUint
anOperationMask = MSocketNotify::EErrorAllOperations
|
A bitmask of MSocketNotify::TOperationBitmasks values specifying which pending operations are affected by the error up-call.
