Hi Anand,
Thanks for your reply. Actually by debugging the code what I am
finding is that..its crashing inside the name_hash(..) func..while
executing line
hash += tolower((unsigned char)(*cp));
I was assuming, there is some problem with my cross compiler..but when
I just wrote a simple program with toLower..its working fine. Since I
am totally new to SNMp so not getting any idea where how to proceed
next.
So any suggestion/guide will be appreciated.
Thanks in advance !
