68 	oslSocketAddr is a pointer to a Berkeley struct sockaddr.
69 	I refrained from using sockaddr_in because of possible further
70 	extensions of this socket-interface (IP-NG?).
71 	The intention was to hide all Berkeley data-structures from
72 	direct access past the osl-interface.
73 
74 	The current implementation is internet (IP) centered. All
75 	the constructor-functions (osl_create...) take parameters
76 	that will probably make sense only in the IP-environment
77 	(e.g. because of using the dotted-address-format).
78 
79 	If the interface will be extended to host other protocol-
80 	families, I expect no externally visible changes in the
81 	existing functions. You'll probably need only new
82 	constructor-functions who take the different address
83 	formats into consideration (maybe a long dotted address
84 	or whatever).
