libssh2_userauth_banner - get the server's userauth banner message

#include <libssh2.h>
libssh2_userauth_banner(LIBSSH2_SESSION *session, char **banner);

session - Session instance as returned by libssh2_session_init_ex(3)

banner - Should point to a pointer that gets filled with banner message.

After an authentication has been attempted, such as a SSH_USERAUTH_NONE request sent by libssh2_userauth_list(3), this function can be called to retrieve the userauth banner sent by the server. If no such banner is sent, or if an authentication has not yet been attempted, returns LIBSSH2_ERROR_MISSING_USERAUTH_BANNER.

On success returns 0 and an UTF-8 NUL-terminated string is stored in the banner. This string is internally managed by libssh2 and will be deallocated upon session termination. On failure returns LIBSSH2_ERROR_MISSING_USERAUTH_BANNER.
