These warnings are quite clear - read them!
Further, the code mib2c generates calls neither 'system' nor 'fscanf' so
this is bugs in code you have written and not included, so we can
obviously not correct it for you.
I would suggest that you look at line 869 and 874 of the file
'ionline.c'.

Actually sir, on these lines there are simple system and fscanf functions are
there...which are perfectly working on normal codes...!!! but here in this
code when I am using inside this mib2c generated code it's not working !!
The code is below... which is working as a stand alone...but not with this
code...
When i am starting subagent wit "net-snmp-config --compile-subagent ionline
ionline.c"
Its showing following warnings..And so qgentX is not starting over here !!
Infect any of the function which returns a lavue..like system call..are not
working inside the code
FILE *pipe = NULL;
char buffer[100];
int j,k;
system("sh jatin.sh > jatin.txt");
pipe=fopen("jatin.txt", "r");
j=fscanf(pipe,"%d",&i);
warning: ignoring return value of 'system', declared with
> attribute warn_unused_result [-Wunused-result]

How can I resolve this problem? I have to make a system call from getting some
values from system,so I can assign them with different OIDS.
Thanks.
