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\n", readnum, ibuf);
         }
         close(insock);
     }
 
 
 }
