Supported system attributes (entities and keys)

The SystemInfo Service API supports the following system attribute entities:

The following tables describe the system attributes supported by the SystemInfo Service API. Read the columns as follows:

Key specifies the name of the system attribute key. Together with the entity, this specifies the system attribute; for example: Battery - BatteryStrength.
Input specifies the system data type for an input value. The type name is used as the name of the SystemData object property that specifies the system attribute value; for example: SystemData.Status (number) or SystemData.DriveInfo (object). NA indicates that no input is applicable.
Output specifies the system data type for an output value.
Value optionally describes the value or the value range of the system attribute, or provides an example value. This is used for both input, if valid, and output. For detailed information about system attribute values, see section System data types.
GetInfo, SetInfo, and GetNotification indicate whether the system attribute supports the GetInfo, SetInfo, and GetNotification methods, respectively.
GetInfo mode indicates whether the system attribute supports synchronous (Sync) or asynchronous (Async) GetInfo calls.
Capability specifies the Symbian capabilities required of any process that loads the Web Runtime to invoke the SystemInfo Service API and access the system attribute.
