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.
