libssh2 manual libssh2_channel_open_ex(3ssh2) 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.
