#ifndef SOCKETIF_H
#define SOCKETIF_H
/* Revsision 20220608
* - removed obsolete socket_local4() and socket_remote4()
* Revision 20210828, Erwin Hoffmann
* - added socket_accept4()
* Revision 20210226, Erwin Hoffmann
* - removed dependency on ipv4socket (loose coupling)
* - only single socket_tcp() and
* - single socket_udp() function serving both IPv4 + IPv6
* Revision 20181125, Erwin Hoffmann
* - switched to 'uint_t.h'
* - changed 'socket_tcp' --> 'socket_tcp4', 'socket_udp' --> 'socket_udp4'
* - added 'socket_ip6optionskill'
* - reordered and included backword compatible IPv6 calls
* - commented multicast socket declarations
* - enlarged usage for ipv4socket -> dual bind IPv4/IPv6
