bufsize




Size of data area

PXERR_NAME_BUFOVERFLOW




The data area is too short to store the objects name

PXERR_GLOBAL_ILLEGAL_CORE




The requested object is not on the same core








PXERR_SERVICE_NOT_CONFIGURED

DESCRIPTION










PxObjGetName copies the name of objid into the buffer buffer of length bufsize. The result is zero-terminated.






















IMPLEMENTATION GUIDELINES
















Before call






    

  • 

    objid must be a valid PXROS-HR object, which may be checked with one of the following macros
    

    

      

    • 

      PxObjIdIsValid() must be true
      

      • 

    • 

      PxObjIdGet() must not be _PXIllegalObjId.
      

      • 

    • 

      PxObjIdError() must be PXERR_NOERROR otherwise the returned error code has to be interpreted (C).
      

      • 

    

    

    • 

  • 

    buffer points to a valid memory area of bufsize bytes length, where the object’s name is stored.
    

    • 



















After call






    

  • 

    The function returns PXERR_NOERROR if the object’s name could be copied. Any other return value describes an error, which has to be interpreted (C).
    

    • 



















Best Practice






    

  • 

    No restrictions.
