resourcemanager: -Power Resource Manager Framework example

resourcemanager: -Power Resource Manager Framework exampleThis example demonstrates the Power Resource Manager user side -APIs. -

Purpose

The example shows how to use the Power Resource Manager user -side APIs provided by the RBusDevResManUs class.

The -use cases demonstrated are:

How to get information about power resources.
How to get information about other clients registered with the Power -Resource Manager.
How to change the state of a resource.
How to get notification when a resource changes state.

Design and implementation

This example builds a -console application called resourcemanager.exe. It requests -user input, and prints information to the console.

The following menu -options are presented to the user:

Get Power Resource information.
Change the state of -a resource.
Notify a change of resource -state.

Get Power Resource information

This option gets and -displays information about the clients of the Power Resource Manager framework -and about the available resources.

The following sub-menu options -are presented:

1. Get the number of -available resources.
2. Get information about -a particular resource.
3. Get information about -all the available resources.
4. Get the state of -a particular resource.
5. Get the number of -clients using a particular resource.
6. Get the number of -resources used by a particular client.
7. Get information about -all the resources in use by a particular client.
8. Get information on -all clients using a particular resource.
9. Get the names of -all clients.

Change the state of a resource

This option allows -the user to change the state of a resource.

Notify any change of -resource state

This option changes the state of a resource and -notifies the user about the change.

Building and configuring

To build the example:

You can build the example -from your IDE or the command line.

If you use an IDE, import the bld.inf file -of the example into your IDE, and use the build command of the IDE.

If -you use the command line, open a command prompt, and set the current directory -to the source code directory of the example. You can then build the example -with the SBSv1 build tools with the following commands:

bldmake -bldfiles

abld build

How to use bldmake and How to use abld describe -how to use the SBSv1 build tools.
For the emulator, the -example builds an executable called resourcemanager.exe in -the epoc32\release\winscw\<udeb or urel>\ folder.

Running the example

To run the example, launch -the executable resourcemanager.exe, then choose from -the menu options. Press Esc to quit.

Note: -this example requires an LDD, a PDD and a PSL (platform specific layer). If -these are not provided on the platform you are using, the example will not -run.
