Inet & Sockets Unit v1.04.
/c/ 2000, 2001 by madded2 (madded@vao.udmnet.ru).
based on units from SIBYL & infos from Toolkit 4.0.
for help use tcppr.inf and C samples from toolkit.
without res_* and dh_* funcs, and have very
bad suppot for select() and ioctl() funcs
new in ver 1.04 : little ioctl() & iptrace support + errors SOCE* constants
new in ver 1.03 : used inet_lib.lib file for fixing VP linker bug
new in ver 1.02 : $saves sections, need for correct registers operations
new in ver 1.01 : ip header struct
}

This is functions from SO32DLL.DLL. These functions allows to use
protocol-independed sockets. Equal to SYS\SOCKET.H, NERRNO.H, SYS\SYSCTL.H.
