Great. I had stuck it below the includes...

Thanks again

Hi Eric,

Using '#define' should work, just make sure you define it prior to
any #include statement that might try to make use of the macro. In my
small version of the testcase I just defined it before all the #include
statements and it worked fine.

-------------------- Example ----------------------------
#define __STDC_WANT_DEC_FP__
#include <stdlib.h>
#include <stdio.h>

int main(void) {
char *dfpstring = "3.1415926This stopped it";
char *stopstring;
_Decimal64 dfp;

dfp = strtod64(dfpstring, &stopstring);
printf(" strtod = %Df\n", dfp);
return 0;
}
-------------------- End example ------------------------
Thanks,

Aaron Albertson

Thanks Aaron,

That works. Just wondering, I had previously tried to manually define
this macro simply as
#define __STDC_WANT_DEC_FP__

... but not on the CRTCMOD.

That had the effect that the conditional compilation like so

#if (__OS400_TGTVRM__ >= 610) && defined __STDC_WANT_DEC_FP__ &&
defined __IBM_DFP__
dfpstring = malloc(fldqry->len + 1 );
memcpy(dfpstring, fldqry->data, fldqry->len);
dfpstring[fldqry->len] = '\0';
record->ORDEXCRATE = strtod64(dfpstring, &stopstring);
free(dfpstring);
#endif

did happen, but still the prototype could not be found.
Is this difference between the defines working as designed?

Regards,
Erik

Hi Erik,

This isn't documented well in the manual, but the 'what' in 'what
defines this macro' is you. This is intended to give the developer some
control about whether the entry points are visible. To get the testcase
to
work just add DEFINE('__STDC_WANT_DEC_FP__') to your CRTCMOD compile
command.

Thanks,

Aaron Albertson

Thanks again for the tip.

It seems like the __STDC_WANT_DEC_FP__ macro is not defined and that
this is the cause of the prototype not being found. I anyone knows
what defines this macro please let me know.

Harumph!

I've been away today due to travel. You can exercise the PPSRCFILE
and/or
PPSRCSTMF parameters to write out the preprocessed source. I would next
try
that, and then search it for the proto. Dunno... I'm grasping at straws
here. Wish I had a couple of jumper cables, 'cuz they'll latch onto
anything.

Hmm, wrapped conditional compiler directives around the code so it
only tries to compile if these macros are in effect. They are, and
still no prototype found.
