Top Forums Programming socket problems with cc compile options??? Post 302188862 by googling2000 on Thursday 24th of April 2008 11:40:37 AM

I don't think the code is to blame here.
I'm wondering if there is some compiler option that I'm not setting properly.

Remember the client code works fine.
I can execute it manually from the command line.
I can stick it into a shell script and execute it fine from there too.
I can run it from a program and it works great.
I can run is a differnt user, no problem.

The server code works fine too.
No problems with 400K launches per month, for the last 10 years.
It has no problems launching other binaries or shell or perl scripts.

Is there some option that "helps" compile a socket program that must run withing a socket program?
Like maybe I need to include some libraries on the compile line or some flags telling it "remember you have to live with some other sockets here"

listen(3SOCKET) 					     Sockets Library Functions						   listen(3SOCKET)

NAME
listen - listen for connections on a socket SYNOPSIS
cc [ flag ... ] file ... -lsocket -lnsl [ library ... ] #include <sys/types.h> #include <sys/socket.h> int listen(int s, int backlog); DESCRIPTION
To accept connections, a socket is first created with socket(3SOCKET), a backlog for incoming connections is specified with listen() and then the connections are accepted with accept(3SOCKET). The listen() call applies only to sockets of type SOCK_STREAM or SOCK_SEQPACKET. The backlog parameter defines the maximum length the queue of pending connections may grow to. If a connection request arrives with the queue full, the client will receive an error with an indication of ECONNREFUSED for AF_UNIX sock- ets. If the underlying protocol supports retransmission, the connection request may be ignored so that retries may succeed. For AF_INET and AF_INET6sockets, the TCP will retry the connection. If the backlog is not cleared by the time the tcp times out, the connect will fail with ETIMEDOUT. RETURN VALUES
A 0 return value indicates success; -1 indicates an error. ERRORS
The call fails if: EBADF The argument s is not a valid file descriptor. ENOTSOCK The argument s is not a socket. EOPNOTSUPP The socket is not of a type that supports the operation listen(). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |MT-Level |Safe | +-----------------------------+-----------------------------+ SEE ALSO
accept(3SOCKET), connect(3SOCKET), socket(3SOCKET), attributes(5), socket.h(3HEAD) NOTES
There is currently no backlog limit. SunOS 5.11 8 Nov 1999 listen(3SOCKET)
