libssh2_session_banner_set3

Set the ssh protocol banner for the local client

Usage

#include <libssh2.h>
int
libssh2_session_banner_set(LIBSSH2_SESSION *session, const char *banner);

Overview

session - Session instance as returned by libssh2_session_init_ex(3)

banner - A pointer to a zero-terminated string holding the user defined banner

Set the banner that will be sent to the remote host when the SSH session is started with libssh2_session_handshake(3) This is optional; a banner corresponding to the protocol and libssh2 version will be sent by default.

Return value

Returns 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.
