#include <sys/types.h>
#include <netdnet/dn.h>
#include <netdnet/dnetdb.h>
#include <stdio.h>
int main(int argc, char **argv)
{
int insock, readnum;
char ibuf[1024];
// Wait for something to happen (or check to see if it already has)
insock = dnet_daemon(0, "GROT", 0, 0);
if (insock > -1)
{
dnet_accept(insock, 0, 0, NULL);
while (!dnet_eof(insock))
{
readnum=read(insock,ibuf,sizeof(ibuf));
fprintf(stderr, "%-*s\\n", readnum, ibuf);
}
close(insock);
}
}
