UserService library

The UserService library is used for accessing information on system users as well as applying user settings like volume.

Known Macros

The system has it's own user ID, being 0xFF.

#define ORBIS_USER_SERVICE_USER_ID_SYSTEM 0xFF

One can also set priority levels on users. The lowest priority is 0x2FF where the highest is 0x100. The sweet spot / normal is 0x2BC.

#define ORBIS_KERNEL_PRIO_FIFO_LOWEST  0x2FF
#define ORBIS_KERNEL_PRIO_FIFO_NORMAL  0x2BC
#define ORBIS_KERNEL_PRIO_FIFO_HIGHEST 0x100

Known Structures

OrbisUserServiceInitializeParams

The service initialize parameters structure is used to initialize the user service library. The parameters only include one known parameter, being the priority.

typedef struct OrbisUserServiceInitializeParams {
	uint32_t priority;
} OrbisUserServiceInitializeParams;

OrbisUserServiceLoginUserIdList

The service login user ID list structure is used as a container for a list of 4 potential user IDs currently logged in on the system.

typedef struct OrbisUserServiceLoginUserIdList {
	OrbisUserServiceUserId userId[4];
} OrbisUserServiceLoginUserIdList;
