PxSysInfoGetInterruptInfo()

Function to get interrupt info.

APPLIES TO

8.2.0

SYNOPSIS
PxError_t PxSysInfoGetInterruptInfo (PxInfoInterrupt_t *InterruptInfo, PxInterrupt_t interruptId);
ARGUMENTS






InterruptInfo




Pointer to data area to store interrupt information to


















interruptId




Id of interrupt object

















RETURN VALUES






    

  • 

    PXROS error code
    

    • 







ERROR CODES















PXERR_INTERRUPT_ILLINTERRUPT




The given object is no interrupt object








PXERR_PROT_PERMISSION




The task has no write permission on the InterruptInfo object









DESCRIPTION










PxSysInfoGetInterruptInfo stores the contents of the interrupt structure interruptId into the info structure InterruptInfo. The structure InterruptInfo has the following format:
















typedef struct
{
	PxUInt_t  PxInfoInterrupt_Number; // interrupt number
	void     (*PxInfoInterrupt_Handler) (PxArg_t); // interrupt handler function
	PxULong_t PxInfoInterrupt_Param; //interrupt handler function’s arguments
	PxTask_t  PxInfoInterrupt_RequestingTask; // task which requested the interrupt object
} PxInfoInterrupt_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






    

  • 

    InterruptInfo must be a pointer to a valid data area.
    

    • 

  • 

    interruptId must be a valid PXROS-HR interrupt object created with a PxInterruptRequest call (V). The validity of interruptId may also be checked by the PxInterruptIsValid 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).
    

    • 



















Best Practice






    

  • 

    No restrictions

USAGE








#include "pxdef.h"

PxError_t err = PxSysInfoGetInterruptInfo(&InterruptInfo, interruptId);

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