The function

fills the transport, the port number and the community strings with
reasonable default values when they are not specified.
The default transport
is

If the host name contains a slash the default is modified to

* The host or ip is either an IPv4 address (as parsed by inet_pton()), an
* IPv6 address in '[' and ']' and parseable by inet_aton() or a hostname
* terminated by the last colon or by the NUL character.
*
* The port number may be specified numerically or symbolically and starts
* with the last colon.
*
* The functions sets the chost, cport, trans, read_community and
* write_community fields on success and the error field on errors.
* The chost and cport fields are allocated by malloc(3), their previous
* content is deallocated by free(3).
*
* The function explicitly allows mismatches between the transport and
* the address type in order to support IPv4 in IPv6 addresses.
