Type Documentation

enum QService::Scope

Defines the scope to be used when accessing services. Note that Symbian does not distinguish scopes and therefore UserScope and SystemScope may be used interchangeably.

Constant	Value	Description
`QService::UserScope`	`0`	When adding and removing services, uses a storage location specific to the current user. When searching for services and interface implementations, first searches in the user-specific location; if the service or interface implementation is not found, searches in the system-wide storage location (if the user has sufficient permissions to do so).
`QService::SystemScope`	`1`	When adding and removing services, use a system-wide storage location accessible to all users. When searching for services and interface implementations, search only in the system-wide storage location.

enum QService::Type

Defines the type of the service

Constant	Value	Description
`QService::Plugin`	`0`	This denotes that the service is plug-in based.
`QService::InterProcess`	`1`	This denotes that the service is deployed using IPC mechanisms available on the current platform, such as DBus or local sockets.

enum QService::UnrecoverableIPCError

Defines the unrecoverable IPC error of the service

Constant	Value	Description
`QService::ErrorUnknown`	`0`	An unknown IPC error.
`QService::ErrorServiceNoLongerAvailable`	`1`	Indicates that the service is no longer available.
`QService::ErrorOutofMemory`	`2`	Indicates that the service is out of memoruy.
`QService::ErrorPermissionDenied`	`3`	Indicates that the permission of this service is denied.
`QService::ErrorInvalidArguments`	`4`	User uses invalid argument for this service.
