Re: Check existence of data area in ILE C

   Hi Jevgeni,

   I realized that every call to Check_DTAARA when data area not exists,
   creates error lines in job log like this (which almost fired me out):
    Cannot resolve to object DTANAME. Type and Subtype X'190A' Authority
      X'0000'.

   Do you have quick solution to avoid of message in job log ?

   Regards,

   Zvi

     I tried this function and it works fine!
     I only added these 2 includes:
     #include <except.h>
     #include <mih/rslvsp.h>

     Thank you all,

     Zvi

 I use a function Check_DAARA before calling RTVDTAARA:

 int Check_DTAARA(char *dtaname, char *dtalib)
 {
   _SYSPTR p;
   volatile _INTRPT_Hndlr_Parms_T ca; /* communications area */

   #pragma exception_handler(ERROR_OCCURED, ca, 0, _C2_MH_ESCAPE, \
                             _CTLA_HANDLE, "MCH3401")

   p = rslvsp(WLI_DTAARA, dtaname, dtalib, 0x0190);
   return 0;

   ERROR_OCCURED:
   return -1;
 }

 Returns 0 if data area exists, otherwise -1.
 Requires some includes.
 Can be used as a generic exception handler.
 It is actually made of an example in one of the manuals (ILE/C
 programmers's guide or alike).

    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.
