Function Documentation

int gj_idmgr_load ( Gj_Idmgr * mgr, Gj_Id * global, Gj_Id * local )

Try to load the actual ids. Returns: 0 on success -1 if we cannot access the data, -2 if the data did not exist (but the dataset has now been created and gj_idmgr_save can be applied on it) For internal use only.

int gj_idmgr_save ( Gj_Ctx * ctx, Gj_Id * global, Gj_Id * local )

Try to save the actual ids. Returns: 0 on success, -1 if the data could not be saved. For internal use only.

void gj_idmgr_assignMACToSysid ( unsigned char * mac, Gj_Sysid * sysid )

Assign a MAC of type 'char mac[6]' to a sysid. For internal use only.

int gj_idmgr_createSystemIdFromMAC ( Gj_Idmgr * mgr, Gj_Sysid * sysid )

Try to create a unique system id from the MAC address of an ethernet card. Returns: 0 on success, -1 otherwise.

int gj_idmgr_createSystemId ( Gj_Idmgr * mgr, Gj_Sysid * sysid )

Try to create a unique system id. Returns: 0 on success, -1 otherwise. For internal use only.

int Gj_idmgr_new ( Gj_Ctx * ctx )

Create a new id manager. Returns: 0 on success, -1 otherwise.

int gj_idmgr_open ( Gj_Ctx * ctx, Gj_Id * global, Gj_Id * local )

Do the loading or creating process for the dataset. Returns: 0 on success, -1 otherwise. For internal use only.

int gj_idmgr_close ( Gj_Ctx * ctx )

Close the data set. For internal use only.

int Gj_idmgr_createId ( Gj_Ctx * ctx, Gj_Id * id )

Create a new world-wide unique id. Returns: 0 on success, -1 otherwise.

int Gj_idmgr_createLocalId ( Gj_Ctx * ctx, Gj_Id * id )

Create a new local-unique id. Returns: 0 on success, -1 otherwise.

int Gj_idmgr_getSysid ( Gj_Ctx * ctx, Gj_Sysid * sysid )

Get the system id. Returns: 0 on success, -1 otherwise.
