DNET_EOF(3)						     Library Functions Manual						       DNET_EOF(3)

NAME
       dnet_eof - Is DECnet socket at End of File ?

SYNOPSIS
       #include <netdnet/dn.h>
       #include <netdnet/dnetdb.h>

       int dnet_eof (int fd)

DESCRIPTION
       dnet_eof  returns  0 if the socket is not at end-of-file.  It will return -1 otherwise, errno will be set accordingly. errno will be set to
       ENOTCONN if the socket is at EOF.
       dnet_eof is only supported on Linux 2.4.0 or later. On earlier kernels it will always return -1 and errno will be set to EINVAL.

EXAMPLE
       Here is a primitive server example that just prints out anything sent to it from the remote side:
       #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
", readnum, ibuf);
	       }
	       close(insock);
	   }

       }
