oslSocketAddr is a pointer to a Berkeley struct sockaddr.
I refrained from using sockaddr_in because of possible further
extensions of this socket-interface (IP-NG?).
The intention was to hide all Berkeley data-structures from
direct access past the osl-interface.
The current implementation is internet (IP) centered. All
the constructor-functions (osl_create...) take parameters
that will probably make sense only in the IP-environment
(e.g. because of using the dotted-address-format).
If the interface will be extended to host other protocol-
families, I expect no externally visible changes in the
existing functions. You'll probably need only new
constructor-functions who take the different address
formats into consideration (maybe a long dotted address
or whatever).
