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 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.

LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.

LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED -
