It supports the berkeley sockets API, but relies on the features of the u= nderlying OS to implement it, so it cannot do anything that windows itself = does not support (though it may be it more or less easy to access certain f= unctionality using one API or the other). > 4.

There is a bit of overhead, but not a great deal; most of cygwin's implem= entations of the berkeley sockets APIs are just fairly thin wrappers around= calls to the underlying winsock functionality that is used to implement th= em. cheers, DaveK --=20 Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
