Re: _Rwrite and _RIOFB_T->dup_key

FYI

I solved the problem myself. I can use exception_handler here.
A little issue - joblog still shows "duplicate key..." despite of _CTLA_HANDLE_NO_MSG (handle and do not log message)

#include <recio.h>
#include <stdio.h>
#include <errno.h>
#include <except.h>

void main(void) {
char buffer[9999];
_RFILE *file1 = _Ropen("<some file keyed with UNIQUE=Yes>", "rr+,dupkey=Y");
_RFILE *file2 = _Ropen("<same file as here ^>", "rr+,dupkey=Y");
_RIOFB_T *fb;

fb = _Rreadf(file1, buffer, file1->buf_length, __NO_LOCK);

#pragma exception_handler(dup_key_error,0,0,_C2_MH_NOTIFY,_CTLA_HANDLE_NO_MSG,"CPF5034")
fb = _Rwrite(file2, buffer, file2->buf_length);

if(0) {
dup_key_error:
printf("Duplicate key found\n");
}

return;
}


Regars,
Alexei

Hello everyone!

I encountered a problem - the _Rwrite does not set the dup_key in _RIOFB_T, when writing a duplicate unique value to unique keyed file.
Tried on several servers, same result everywhere. Has anyone encountered something similar?

My code is simple:

#include <recio.h>
#include <stdio.h>
#include <errno.h>

void main(void) {
char buffer[9999];
_RFILE *file1 = _Ropen("<some file keyed with UNIQUE=Yes>", "rr+,dupkey=Y");
_RFILE *file2 = _Ropen("<same file as here ^>", "rr+,dupkey=Y");
_RIOFB_T *fb;

fb = _Rreadf(file1, buffer, file1->buf_length, __NO_LOCK);
fb = _Rwrite(file2, buffer, file2->buf_length);

// Joblog says "Duplicate key on access path"
// fb->num_bytes==0
// BUT: fb->dup_key==0!
// Where I'm wrong?????

return;
}
