libssh2_userauth_password_ex - authenticate a session with username and password

session - Session instance as returned by libssh2_session_init_ex(3)username - Name of user to attempt plain password authentication for.

       username_len - Length of username parameter.

       password - Password to use for authenticating username.

       password_len - Length of password parameter.

       passwd_change_cb  -  If  the  host accepts authentication but requests that the password be changed, this
       callback will be issued.  If no callback is defined, but server required password change,  authentication
       will fail.

       Attempt  basic  password  authentication.  Note  that  many  SSH servers which appear to support ordinary
       password authentication actually have it disabled and use Keyboard Interactive authentication (routed via
       PAM or another authentication backed) instead.

       Some of the errors this function may return include:

       LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_PASSWORD_EXPIRED -

       LIBSSH2_ERROR_AUTHENTICATION_FAILED - failed, invalid username/password or public/private key.

       libssh2_userauth_password_ex - authenticate a session with username and password

       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.
