Hello,

 

I was relieved to find the solution of an asyn problem I had (behavior change from 4-26 to 4-27).

(https://epics.anl.gov/tech-talk/2015/msg01713.php)

 

Now, when I use the code,

   setParamStatus(param, ASYN_SUCCESS);  /* If it might previously have been an error code */

   setXXXParam(param, value);

   callParamCallbacks();

   setParamStatus(param, ASYN_ERROR);  /* Or other error */

  callParamCallbacks();

does not update the value of my parameter,

 

but with this version (using callParamCallbacks(0); instead of callParamCallbacks();)

   setParamStatus(param, ASYN_SUCCESS);  /* If it might previously have been an error code */

   setXXXParam(param, value);

   callParamCallbacks(0);

   setParamStatus(param, ASYN_ERROR);  /* Or other error */

  callParamCallbacks(0);

the parameter value is updated.

 

Do you have any idea for such a behavior ?

 

I am using asyn4-32.

 

Sébastien.
