Re: Check existence of data area in ILE C

Gary's suggestion is better than mine!  I forgot about the QWCRDTAA API.
It takes care of the exception handling for you and exposes any errors via
the "error code" parameter.

		Thanks,

Aaron

Use the QWCRDTAA API instead of QXRTVDA?

   My ILE C program crashes in the line of QXXRTVDA if data does not exist.
   Is there a way to avoid this crash ?
   Someone has an example code for this?

   The line is like this:
   QXXRTVDA(dta, 41, 5, user_dta);
   and I got program crash with the message:
    "Data area DTA in QGPL not found."

   If data area dta exists, it works fine.

   Regards,

   Zvi
