Hi. I need to add code to my KSH script to automatically assign an open port number from a pre-defined range to an Oracle listener.

SYNOPSIS
#include <libssh2.h>
LIBSSH2_LISTENER * libssh2_channel_forward_listen_ex(LIBSSH2_SESSION *session, char *host, int port, int *bound_port, int queue_maxsize);
LIBSSH2_LISTENER * libssh2_channel_forward_listen(LIBSSH2_SESSION *session, int port);

host - specific address to bind to on the remote host. Binding to 0.0.0.0 (default when NULL is passed) will bind to all available
addresses.
port - port to bind to on the remote host. When 0 is passed, the remote host will select the first available dynamic port.
bound_port - Populated with the actual port bound on the remote host. Useful when requesting dynamic port numbers.
queue_maxsize - Maximum number of pending connections to queue before rejecting further attempts.
libssh2_channel_forward_listen(3) is a macro.
RETURN VALUE
A newly allocated LIBSSH2_LISTENER instance or NULL on failure.
ERRORS
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_PROTO - An invalid SSH protocol response was received on the socket.
LIBSSH2_ERROR_REQUEST_DENIED - The remote server refused the request.
LIBSSH2_ERROR_EAGAIN - Marked for non-blocking I/O but the call would block.
