cfgmgr_set_status(9r) cfgmgr_set_status(9r)NAMEcfgmgr_set_status - General: Reports failure to the cfgmgr frameworkSYNOPSISint cfgmgr_set_status( char *driver_name );ARGUMENTSSpecifies the name of the device driver for which you want to report an associated failure. This name is a string that matches the string you specified for the entry_name item in the /etc/sysconfigtab database. Typically, third-party driver writers specify the driver name (followed by a colon) in the sysconfigtab file fragment, which gets appended to the /etc/sysconfigtab database during the driver product installation.DESCRIPTIONThe cfgmgr_set_status routine reports to the cfgmgr framework that a failure has occurred during static configuration. If the specified device driver is in the static configuration state, it does not know that the configuration operation is complete until all register call- back requests (routines) have successfully completed. Therefore, a device driver calls cfgmgr_set_status to report a possible failure dur- ing static configuration to the cfgmgr framework. Specifically, cfgmgr_set_status performs the following failure operations: Adjusts the state of the specified device driver Unconfigures the specified device driver from the cfgmgr framework The cfgmgr_set_status routine calls the device driver's configure routine at its CFG_OP_UNCONFIGURE entry point as part of these failure operations. The code associated with the CFG_OP_UNCONFIGURE entry point is responsible for determining how to deallocate any allocated resources during these failure operations. The cfgmgr_set_status routine does not notify the operator of a configuration failure. Part of the code associated with the CFG_OP_UNCON- FIGURE entry point could include an error logging operation to record the fact that a failure has occurred. The reason for doing this is that the cfgmgr framework's task is to accomplish the unconfigure operation of a statically configured device driver. You call the cfgmgr_set_status routine in the device driver's callback routine when the static configuration operation fails. You register a callback routine by calling the register_callback routine.RETURN VALUESUpon successful completion, cfgmgr_set_status returns the value ESUCCESS. This success value indicates that cfgmgr_set_status adjusted the state of the device driver and caused the cfgmgr framework to unconfigure the driver. Otherwise, cfgmgr_set_status returns one of the fol- lowing error constants defined in /usr/sys/include/sys/sysconfig.h and /usr/sys/include/sys/errno.h: The device driver that you specified in the driver_name argument does not exist. In this case, cfgmgr_set_status cannot adjust the state and unconfigure the device driver. The device driver that you specified in the driver_name argument was not statically configured. The device driver that you specified in the driver_name argument is not in the static configuration state.EXAMPLESSee Writing Device Drivers: Tutorial for a code example of the cfgmgr_set_status interface.SEE ALSORoutines: cfgmgr_get_state(9r), register_callback(9r) cfgmgr_set_status(9r)
