Hi,

The function init_snmp is prototyped as a void function but can generate
errors.

Example:
If I set an invalid address in the variable NETSNMP_DS_AGENT_X_SOCKET, an
error is triggered in init_snmp:
Error: Failed to connect to the agentx master agent
(tcp:TEST_UNKONOWN_HOST:1450): Unknown host (tcp:ptxskplus55:1450) (No such
file or directory)

How can I catch this error ? Is there a function in net-snmp that checks for
errors arising in init_snmp ?

Thanks

Arnaud.

The only work-around I found is to test the return code of the function
register_int_index, which fails if it is unable to connect to the master
agent.

I would prefer to catch the error message displayed in the function
subagent_open_master_session.

This is not possible?

No - I don't believe this is possible.
(And I'm not immediately sure how we could sensibly address this issue).

Can I suggest that you log this on the project tracker system (either
as a bug, or a feature request), so that it doesn't get lost in the
mailing list archives.
