PxSysInfoGetDelayInfo()

Function to get delay info.

APPLIES TO

8.2.0

SYNOPSIS
PxError_t PxSysInfoGetDelayInfo (PxInfoDelay_t *DelayInfo, PxDelay_t delayId);
ARGUMENTS






DelayInfo




Pointer to data area to store delay information to


















delayId




Id of delay object

















RETURN VALUES






    

  • 

    PXROS error code
    

    • 







ERROR CODES















PXERR_DELAY_ILLDELAY




The given object is no delay object








PXERR_PROT_PERMISSION




The task has no write permission on the DelayInfo object









DESCRIPTION










PxSysInfoGetDelayInfo stores the contents of the delay structure delayId into the info structure DelayInfo. The structure DelayInfo has the following format:
















typedef struct
{
	PxInfoDelayType_t PxInfoDelay_Type; // delay type
	void      (*PxInfoDelay_Handler) (PxArg_t); // delay handler function
	PxULong_t PxInfoDelay_Param; // delay handler function’s arguments
	PxULong_t PxInfoDelay_Ticks; // delay ticks
	PxULong_t PxInfoDelay_RestTicks; // delay rest ticks
	PxTask_t  PxInfoDelay_RequestingTask; // task which requested the delay object
} PxInfoDelay_t;
















The delay object delayId may have one of the following types:
















typedef enum
{
	DelayType_InUse,
	DelayType_NotUsed
} PxInfoDelayType_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






    

  • 

    DelayInfo must be a pointer to a valid data area.
    

    • 

  • 

    delayId must be a valid PXROS-HR delay object created with a PxDelayRequest call (V). The validity of delayId may also be checked by the PxDelayIsValid macro (F). The delay object must be created on the same core as the caller runs on. The creator core id can be read with the macro PxDelayCoreId and the own core id with PxGetCoreId (C).
    

    • 



















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).

USAGE








#include "pxdef.h"

PxError_t err = PxSysInfoGetDelayInfo(&DelayInfo, delayId);

if (err == PXERR_NOERROR) {
    // Handle info
}
else {
    // Report error
}
