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