int libssh2_banner_set(LIBSSH2_SESSION *session, const char *banner);
This function is DEPRECATED. Use libssh2_session_banner_set(3) instead!
session - Session instance as returned by libssh2_session_init_ex(3)
banner - A pointer to a 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 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 isn't really a failure per se.
Marked as deprecated since 1.4.0
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
