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.

|
|
|
~~~c
|
|
#include <libssh2.h>
|
|
|
|

# DESCRIPTION
|
|
|
|
*channel* - Previously opened channel instance such as returned by
|
|
libssh2_channel_open_ex(3).
|
|
|
|
*single_connection* - non-zero to only forward a single connection.
|
|
|
|
*auth_proto* - X11 authentication protocol to use
|
|
|
|
*auth_cookie* - the cookie (hexadecimal encoded).
|
|
|
|
*screen_number* - the XLL screen to forward
|
|
|
|
Request an X11 forwarding on *channel*. To use X11 forwarding,
|
|
libssh2_session_callback_set2(3)
|
|
must first be called to set **LIBSSH2_CALLBACK_X11**. This callback will be
|
|
invoked when the remote host accepts the X11 forwarding.
|
|
|
|
# RETURN VALUE
|
|
|
|
Return 0 on success or negative on failure. It returns
|
|
LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
|
|
LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
|
|
|
|
# ERRORS
|
|
|
|
*LIBSSH2_ERROR_ALLOC* - An internal memory allocation call failed.
|
|
|
|
*LIBSSH2_ERROR_SOCKET_SEND* - Unable to send data on socket.
|
|
|
|
*LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED* -
