Re: [foxboro] Problems in C programs with FoxApi

Hi Alexsis,
It looks to me that the nom_tmp(100) is smaller that all the other
arrays(612).
What is the maxobj for foxapi set to?
What are the errors you get?

I would like to suggest to start off with a small number of tags like 2 to 5
or so and iron out all problems first before you go for the full size of
what you want/need. 

Regards,
Frits Schouten.

Subject: [foxboro] Problems in C programs with FoxApi


Hello,

I try to create a C program for Foxboro and i need advise.
I use the Foxapi and the scopen and bread functions.

I get errors when opening set in read write. The set had 612 tags. I have no
problem when opening it in read only.
I tried different maner to open it: 

 - splitting it in 100 tags sets
 - using sbopen,scopen, setting sleeps between the scopens.

non of this trick work. The result is that my program locks up and i need to
kill it manually (not with a -KILL) to stop it.
but when sometimes it works, the write fonction bwrite works perfecty. but
when it wors and i close the sets, it is therefor totaly impossible to
reopen the sets because it open them with no connection errors (-1); I look
into the omlist with the som program and when i call the clsset fonction,
the omlist are not destoy like they are with a read only open.

does someone have any sugestion to help me ??

i copy here the open fonction and the parametres used :

#include <foxapi.h>

/* Definition du type tag facilitant l'ecriture */
typedef char tag[AN_ONAM_SIZ];

tag nom_tmp[100];

int set;
int acctyp = 2; 
int rsr = 5;
int wsr = 10;
int clexit = 1;
int reterr;

int gw_cp[612];
int valtyp_cp[612];
float rdelta_cp[612];
int error_cp[612];
float wdelta_cp[612];
int nument_cp = 612;
int index_cp [612];
int status_cp [612];

for (i=0;i<612;i++) {
        valtyp_cp[i] = 5;
        rdelta_cp[i] = 1.0;
        wdelta_cp[i] = 1.0;
        gw_cp[i]=1;
        }

scopen (gw_cp, nument_cp, nom_tmp, valtyp_cp, acctyp, rdelta_cp, clexit,
rsr, wsr, wdelta_cp, &set, index_cp, error_cp, &reterr);
printf("scopen cp%d reterr = %d, set %d\n",i,reterr,set);


thank you for any help
