KwikNet TCP/IP Sockets

Returns If successful, a non-negative socket descriptor is returned.

On failure, the error status

-1 is returned.

If a socket cannot be created, the error indicator defining the reason for

failure cannot be recorded. You cannot use

kn_errno() to retrieve the

error code since you have no socket descriptor to interrogate. The

following error codes, although not available for testing, still define the

possible reasons for failure.

EPROTONOSUPPORT The socket type or the specified protocol is not

supported within the domain.

EMFILE No more sockets are available. Close some sockets

or revise your KwikNet configuration to provide more.

ENOBUFS Resources needed to create a socket are unavailable.

Restriction Sockets of type SOCK_RAW cannot be used unless you have configured your

KwikNet libraries to allow support raw sockets. Edit your KwikNet Network

Parameter File and check the box labeled "Use raw sockets" on the TCP

property page.
