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
|
|
|
|
*channel* - Previously opened channel instance such as returned by
|
|
libssh2_channel_open_ex(3)
|
|
|
|
*varname* - Name of environment variable to set on the remote
|
|
channel instance.
|
|
|
|
*varname_len* - Length of passed varname parameter.
|
|
|
|
*value* - Value to set varname to.
|
|
|
|
*value_len* - Length of value parameter.
|
|
|
|
Set an environment variable in the remote channel's process space. Note that
|
|
this does not make sense for all channel types and may be ignored by the
|
|
server despite returning success.
|
|
|
|
# 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* -
