Hello,
I am just concerned about how to add a new socket fd for socket communication
with alarm Application to existing fd list netsnmp is listening for.
Manager
||
||
Alarm Application ======Agent
For this i tried :
main()
{
init_agent("snmpV3Agent");
init_currentAlarmTable();
init_snmp("snmpV3Agent");
... .
........
//start listning for client
listener = socket(AF_INET, SOCK_STREAM, 0);
bind(listener, (struct sockaddr *)&myaddr, sizeof(myaddr));
listen(listener, 10)
while()
{
snmp_select_info(&numfds, &read_fds, NULL, 0);
select(numfds,&read_fds,0,0,NULL)
if (FD_ISSET(listener , &read_fds))
{
//accept when ready to be read
newfd = accept(listener, (struct sockaddr
*)&remoteaddr,&addrlen)
//myfunction1 --->reads the data add it to queue and forward
to manager as a TRAP
register_readfd(&numfds,(*myfunction1),NULL);
}
}
}
or it is that i just need to call snmp_select_info() with readfds containing my
new socket fd and just call register_readfd() and i not even need to check for
FD_ISSET(). This will automatically accept the connection when the fd is ready
to be read and in the function pointer(call back method) i can write the code
to extract the data.
Is it. Please do reply if i am wrong anywhere.
Thanks
