[AGENT++] Dynamic row creation problem

[somenath.pal at wipro.com]

Hi ,

I found the problem. 

Actually  I did not used the latest version of AGENT++ and SNMP++ and in
the earlier version of AGENT++ there is bug which is fixed in latest
version of AGENT++. 

In the function int MibTable::check_creation(Request* req, int& ind)
(mib.cpp) the type of new_row_status is unint32

 

uint32 new_row_status = 0; 

So req->get_value(i).get_value(new_row_status); is calling the  int
Vb::get_value(unsigned long &i) const (vb.cpp) and it is returning error
from this particular function .

 

In the latest version of  the code it is changed to 

 

  int new_row_status = 0;

  req->get_value(i).get_value(new_row_status); 

 

Regards,

Somenath
