.Fa resp .
If no reponse could be received after all timeouts and retries, the function
returns -1. If a response was received 0 is returned.
.Pp
The function
.Fn snmp_parse_server
is used to parse an SNMP server specification string and fill in the
fields of a
.Vt struct snmp_client .
The syntax of a server specification is
.Pp
.D1 [trans::][community@][server][:port]
.Pp
where
.Va trans
is the transport name (one of udp, stream or dgram),
.Va community
is the string to be used for both the read and the write community,
.Va server
is the server's host name in case of UDP and the path name in case
of a local socket, and
.Va port
is the port in case of UDP transport.
The function returns 0 in the case of success and return -1 and sets
the error string in case of an error.
.Sh DIAGNOSTICS
If an error occures in any of the function an error indication as described
above is returned. Additionally the function sets a printable error string
