Re: init_agent() crashing

Hi Bart,

Thanks for your reply. It did work. But i would like to appreciate if
you would let me know why it works..
 0xff in binary is 11111111.. and by doing  tolower((*cp) & 0xff)..it
will set the corresponding bits which are 1 in (*cp)..
 But how it solved the crashing issue ??

Now again it crashing at  while (*from != 0 && !isspace(*from)) ...
I did !isspace(*from & 0xff) ..but it's not working.. :(
Why its crashing when Its calling all the c -related functions.. Is
there any problem with my cross compiler..??
Would appreciate if you can guide me on this..

Thanks in advance..
