PXERR_PROT_PERMISSION
The task has no write permission on the
ToInfo
objectPXERR_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 aPxToRequest
call (V). The validity oftoId
may also be checked by thePxToIsValid
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).
