NAME
libssh2_channel_open_ex - establish a generic session channel
SYNOPSIS
#include <libssh2.h>
LIBSSH2_CHANNEL * libssh2_channel_open_ex(LIBSSH2_SESSION *session,
const char *channel_type, unsigned int channel_type_len, unsigned int
window_size, unsigned int packet_size, const char *message, unsigned
int message_len);
LIBSSH2_CHANNEL * libssh2_channel_open_session(session);
DESCRIPTION
session - Session instance as returned by libssh2_session_init_ex(3)
channel_type - Channel type to open. Typically one of session, direct-
tcpip, or tcpip-forward. The SSH2 protocol allowed for additional types
including local, custom channel types.
channel_type_len - Length of channel_type
window_size - Maximum amount of unacknowledged data remote host is
allowed to send before receiving an SSH_MSG_CHANNEL_WINDOW_ADJUST
packet.
packet_size - Maximum number of bytes remote host is allowed to send in
a single SSH_MSG_CHANNEL_DATA or SSG_MSG_CHANNEL_EXTENDED_DATA packet.
message - Additional data as required by the selected channel_type.
message_len - Length of message parameter.
Allocate a new channel for exchanging data with the server. This method
is typically called through its macroized form: libssh2_chan-
nel_open_session(3) or via libssh2_channel_direct_tcpip(3) or lib-
ssh2_channel_forward_listen(3)
RETURN VALUE
Pointer to a newly allocated LIBSSH2_CHANNEL instance, or NULL on
errors.
ERRORS
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_CHANNEL_FAILURE -
LIBSSH2_ERROR_EAGAIN - Marked for non-blocking I/O but the call would
block.
