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