libssh2_session_banner_get — get the remote banner
const char *libssh2_session_banner_get(oLIBSSH2_SESSION *session);
Once the session has been setup and libssh2_session_handshake(3) has completed successfully, this function can be used to get the server id from the banner each server presents.
A pointer to a string or NULL if something failed. The data pointed to will be allocated and associated to the session handle and will be freed by libssh2 when libssh2_session_free(3) is used.
