75 oslSocketAddr is a pointer to a Berkeley struct sockaddr.
76 I refrained from using sockaddr_in because of possible further
77 extensions of this socket-interface (IP-NG?).
78 The intention was to hide all Berkeley data-structures from
79 direct access past the osl-interface.
80
81 The current implementation is internet (IP) centered. All
82 the constructor-functions (osl_create...) take parameters
83 that will probably make sense only in the IP-environment
84 (e.g. because of using the dotted-address-format).
85
86 If the interface will be extended to host other protocol-
87 families, I expect no externally visible changes in the
88 existing functions. You'll probably need only new
89 constructor-functions who take the different address
90 formats into consideration (maybe a long dotted address
91 or whatever).
