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);
session - Session instance as returned by
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_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_EAGAIN - Marked for non-blocking I/O but the call would block.
