hi

i am trying to send and recv between 3 processes using udp.

three processes are three passes thr same loop in which i send first and
then receive

but send runs and recv gets transport endpoint not connected error

like i try to recv msgs sent in processes 2 and 3 in process 1 but as they
are diff processes this should work

i dont know why i get this error can anyone enlighten

Only guesses. Did you open socket as SOCK_DGRAM? Do you use 'recvfrom'
function? If you use 'recv', did you 'connect' your udp socket? Read man
udp, maybe this will help you.
