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_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_channel_open_session(3) or via libssh2_channel_direct_tcpip(3)
Pointer to a newly allocated LIBSSH2_CHANNEL instance, or NULL on
