+/*
+ 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-Addr-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 Addr
+ formats into consideration (maybe a long dotted Addr
+ or whatever).
+*/
+
+/*
+ _Note_ that I rely on the fact that oslSocketAddr and struct sockaddr
+ are the same! I don't like it very much but see no other easy way to
+ conceal the struct sockaddr from the eyes of the user.
