SYNOPSIS
       #include <libssh2.h>

       LIBSSH2_CHANNEL *
       libssh2_channel_direct_tcpip_ex(LIBSSH2_SESSION *session,
                                       const char *host, int port,
                                       const char *shost, int sport);

       LIBSSH2_CHANNEL *
       libssh2_channel_direct_tcpip(LIBSSH2_SESSION *session,
                                    const char *host, int port);

DESCRIPTION
       session - Session instance as returned by libssh2_session_init_ex(3)

       host - Third party host to connect to using the SSH host as a proxy.

       port - Port on third party host to connect to.

       shost - Host to tell the SSH server the connection originated on.

       sport - Port to tell the SSH server the connection originated from.

       remains encrypted, communication from the server to the 3rd party host
       travels in cleartext.

RETURN VALUE
       Pointer to a newly allocated LIBSSH2_CHANNEL instance, or NULL on
       errors.

ERRORS
