By preallocating sufficiently large structures we remove any allocations whilst the resource manager mutex is held. |

@param aNClientLevels number of client levels the RM should preallocate. This is roughly the number of clients |
|
1189 |
that are expected to use shared resources multiplied by the number of shared resources. |

Request changing the state of a resource |
|
2401 |
NOTE: If a resource callback is specified for instantaneous resource, then callback |
|
2402 |
will be called after resource change and will be executed in the context of the |
|
2403 |
client thread. |
|
| 244 | 2404 |
If a resource callback is specified for long latency resources, then it will be |
| 0 | 2405 |
executed asynchronously.When the request is accepted the API returns immediately |
2406 |
and the calling thread is unblocked: the callback (called in the client's context) |
|
2407 |
will be invoked when the resource change finally takes place. |
|
2408 |
If aCb is not specified (NULL by default) the API executes synchronously and will |
|
2409 |
only return when the resource change has taken place for long latency resource. |
|
2410 |
The client thread is blocked throughout |
|
2411 |
When state change for a shared resource is requested, only minimum state that |
|
2412 |
satisfy the requirement is guaranteed and it is not guaranteed for the absolute |
|
2413 |
value change. |
|
2414 |
||
2415 |
@param aClientId ID of the client which is requesting the resource change. |
|
2416 |
@param aResourceId ID of the resource whose state is to be changed. |
|
2417 |
@param aNewState The new state of the resource. This could be a binary value for a |
|
2418 |
binary resource, an integer level for a multilevel resource or some |
|
2419 |
platform specific token for a multi-property resource. |
|
2420 |
@param aCb For Long latency resource |
|
2421 |
A pointer to a resource callback object which encapsulates a |
|
2422 |
callback function to be called whenever the resource state change |
|
| 244 | 2423 |
happens (if left NULL the API will execute synchronously). |
| 0 | 2424 |
For Instantaneous resource |
2425 |
A pointer to a resource callback object which encapsulates a callback |
|
2426 |
function to be called after resource change. This executes in the |
|
2427 |
context of the client thread. |
|
2428 |
||
2429 |
@return KErrNone If the API is to be executed synchronously it indicates the change was |
|
2430 |
successful, if the API is to be executed asynchronously it indicates |
|
2431 |
the request to change the resource state has been accepted. |
|
2432 |
KErrNotFound if the resource ID could not be found in the current list of |
|
2433 |
controllable resources. |
|
2434 |
KErrAccessDenied if the client ID could not be found in the list of |
|
2435 |
registered clients or if the client was registered to be thread |
|
2436 |
relative and this API is not called from the same thread or if the |
|
2437 |
resource is single user resource and another client is already holding |
|
2438 |
the resource. |
|
2439 |
KErrNotReady if the request is issued before the resource controller completes its |
|
2440 |
internal initialisation. |
|
2441 |
KErrUnderflow if the client has exceeded the reserved number of |
|
2442 |
SPowerResourceClientLevel and the free pool is empty or if it is |
|
2443 |
an asynchronous operation on a long latency resource and the client has |
|
2444 |
exceeded the reserved number of TPowerRequest and the free pool is empty. |
|
2445 |
KErrArgument if requested level is out of range (outside of min and max levels). |
|
2446 |
KErrCorrupt if internal data structure is corrupted. |
|
2447 |
KErrPermissionDenied if the requested state of the resource is not accepted by its dependents. |

This error is valid only for dependent resource state change in extended version |
