socket problems with cc compile options???
Hi there, a newbie as far as compiling c.
I have a problem, I've ported a fairly simple perl socket program over to c.
I compiled it as follows
cc simplesocket.c -lsocket -lnsl
compiles great, no errors.
When I launch it from the command line, it works great!!!!
However, if I launch this program from within another socket program
( a perl socket server (listener) program, basically doing an exec of this compiled program ).
The server program has no problems launching any other kinds of socket apps.
Is there some option I need to tell the compiler that will tell the program it will be running beneath another socket program????
Once again a newbie, any help appreciated.

supposed to be the contents of the IP header.

Hi everyone,
Question for gurus:
Is there a way for us to determine the options used by a socket?
I basically want to know if SO_KEEPALIVE is enabled on a socket to know if the tcp_keepalive_abort_interval parameter will be used by that connection.
Was I clear enough? :confused:

shutdown(3SOCKET) shutdown(3SOCKET)
NAME
shutdown - shut down part of a full-duplex connection
SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl [ library... ]
#include <sys/socket.h>
int shutdown(int s, int how);
The shutdown() call shuts down all or part of a full-duplex connection on the socket associated with s. If how is SHUT_RD, further receives
are disallowed. If how is SHUT_WR, further sends are disallowed. If how is SHUT_RDWR, further sends and receives are disallowed.
The how values should be defined constants.
0 is returned if the call succeeds.
-1 is returned if the call fails.
The call succeeds unless one of the following conditions exists:
EBADF The s value is not a valid file descriptor.
ENOMEM Insufficient user memory is available for the operation to complete.
ENOSR Insufficient STREAMS resources are available for the operation to complete.
ENOTCONN The specified socket is not connected.
ENOTSOCK The s value is not a socket.
