IMPLEMENTATION GUIDELINES
















Before call






    

  • 

    msgId must be a valid message object, requested via PxMsgRequest…​ or PxMsgEnvelop…​ or received by a PxMsgReceive…​ call (V). This id may be checked with one of the following macros:
    

    

      

    • 

      PxMsgIdIsValid() must be true.
      

      • 

    • 

      PxMsgIdGet() must not be _PXIllegalObjId.
      

      • 

    • 

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

      •

After call






    

  • 

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