libssh2_channel_forward_listen_ex(3)

NAME
libssh2_channel_forward_listen_ex - listen to inbound connections

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);

DESCRIPTION
Instruct the remote SSH server to begin listening for inbound TCP/IP connections. New connections will be queued by the library until accepted by libssh2_channel_forward_accept(3). session - instance as returned by libssh2_session_init(). 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.
