Function to get To info.

APPLIES TO

8.2.0

SYNOPSIS
PxError_t PxSysInfoGetToInfo (PxInfoTo_t *ToInfo, PxTo_t toId);
ARGUMENTS






ToInfo




Pointer to data area to store timeout object information to


















toId




Id of timeout object

















RETURN VALUES






    

  • 

    PXROS error code
    

    • 







ERROR CODES















PXERR_PROT_PERMISSION




The task has no write permission on the ToInfo object








PXERR_TO_ILLTO




The given object is no timeout object









DESCRIPTION










PxSysInfoGetToInfo stores the contents of the timout handler toId into the info structure ToInfo.














The structure ToInfo has the following format:
















typedef struct
{
	PxTask_t PxInfoTo_Task; // task to receive timeout event
	PxEvents_t  PxInfoTo_Event; // timeout event
	PxULong_t  PxInfoTo_Timeout; // timeout period
	PxULong_t  PxInfoTo_RestTicks; // rest ticks
	PxTask_t   PxInfoTo_RequestingTask; // task which requested the to object
} PxInfoTo_t;
















There is a union available containing all sysinfo types:
















typedef union
{
	PxInfoMC_t  McInfo; // memory class information struct
	PxInfoOpool_t  OpoolInfo; // Opool information struct
	PxInfoMsg_t  MsgInfo; // message information struct
	PxInfoMbx_t  MbxInfo; // mailbox information struct
	PxInfoDelay_t  DelayInfo; // delay object information struct
	PxInfoPe_t  PeInfo; // periodic event information struct
	PxInfoTo_t  ToInfo; // timeout object information struct
	PxInfoInterrupt_t  InterruptInfo; // interrupt object information struct
} PxObjInfo_T;
























IMPLEMENTATION GUIDELINES
















Before call






    

  • 

    ToInfo must be a pointer to a valid data area.
    

    • 

  • 

    toId must be a valid PXROS-HR timeout handler object created with a PxToRequest call (V). The validity of toId may also be checked by the PxToIsValid macro (F).
    

    • 



















After call






    

  • 

    The function returns PXERR_NOERROR if the system information could be delivered. Any other return value describes an error, which has to be interpreted (C).
