Member Functions Documentation
CancelRequestFreeMemory()
|
IMPORT_C void
|
CancelRequestFreeMemory
|
(
|
)
|
|
Cancels the asynchronous request for free memory.
Connect()
|
IMPORT_C
TInt
|
Connect
|
(
|
)
|
|
Connects a new session. Sessions must be connected before any other APIs can be used. When the client has finished using a session,
Close()
must be called.
RequestFreeMemory(TInt)
|
IMPORT_C
TInt
|
RequestFreeMemory
|
(
|
TInt
|
aBytesRequested
|
)
|
|
Request that the OOM monitor attempts to free some memory. This function may take several seconds to execute, depending on the memory state. It will not return until the attempt to recover memory has completed.
Parameters
|
TInt
aBytesRequested
|
The number of bytes of free memory that the client requests.
|
RequestFreeMemory(TInt, TRequestStatus &)
Request that the OOM monitor attempts to free some memory. This is an asynchronous version of the request for free memory.
Parameters
|
TInt
aBytesRequested
|
The number of bytes of free memory that the client requests.
|
|
TRequestStatus
& aStatus
|
will be completed when the attempt to recover memory has finished. This may take several seconds, depending on the memory state. On completion, aStatus will be set to KErrNone if the request memory is free. KErrNoMemory if that amount of memory could not be recovered. Other error codes may also be set.

|
|
TInt
|
aPluginId,
|
|
|
TInt
&
|
aBytesAvailable
|
|
|
)
|
|
Request that the OOM monitor attempts to free some memory for an optional allocation. The passed in plugin ID is used to determine the priority for this allocation. Lower priority OOM actions may be executed to free enough RAM for this allocation. This function may take several seconds to execute, depending on the memory state. It will not return until the attempt to recover memory has completed.
Parameters
|
TInt
aBytesRequested
|
The number of bytes of free memory that the client requests.
|
|
TInt
aMinimumBytesNeeded
|
|
|
TInt
aPluginId
|
The ID of the plugin that may delete the allocation in event of low memory.
|
|
TInt
& aBytesAvailable
|
|
RequestOptionalRam(TInt, TInt, TInt, TRequestStatus &)
Request that the OOM monitor attempts to free some memory for an optional allocation. The passed in plugin ID is used to determine the priority for this allocation. Lower priority OOM actions may be executed to free enough RAM for this allocation. This function may take several seconds to execute, depending on the memory state. It will not return until the attempt to recover memory has completed.
Parameters
|
TInt
aBytesRequested
|
The number of bytes of free memory that the client requests.
|
|
TInt
aMinimumBytesNeeded
|
|
|
TInt
aPluginId
|
The ID of the plugin that may delete the allocation in event of low memory.
|
|
TRequestStatus
& aStatus
|
The TRequestStatus (completes with the number of bytes freed (aStatus >= 0) or an error (aStatus <= 0))
|
SetOomPriority(TOomPriority)
Notify the OOM monitor that this application has the specified priority
ThisAppIsNotExiting(TInt)
|
IMPORT_C void
|
ThisAppIsNotExiting
|
(
|
TInt
|
aWgId
|
)
|
|
Notify the OOM monitor that this application is not responding to the EEikCmdExit request to exit the application. This function is used by the Avkon framework's app shutter.
Parameters
|
TInt
aWgId
|
the window group identifier of the app that is not exiting.
|
