To render in Git webviews as-is, to make it easier to edit, verify,
and to sync up with curl.
- add options to not build the `.3` man pages:
- autotools: `--disable-docs`
- cmake: `LIBSSH2_BUILD_DOCS=OFF`
- building `.3` man pages requires Perl after this patch.
- drop `mansyntax` and the shell / `grep` / GNU `man` tool requirements with it.
- scripts and most logic were copied from curl.
- add `cd2nroff` from curl, with edits to relax curl-specific checks.
- used `nroff2cd` (from curl) to convert from `.3` to `.md`. Then
manually fixed copyrights, inline function references and a couple
of other things.

# 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_channel_open_session(3)* or via *libssh2_channel_direct_tcpip(3)*
|
|
or *libssh2_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.
