neon 0.34.2                                       15 April 2025                                  NE_GET_ERROR(3)

       The session error string is used to store any human-readable error information associated with any errors
       which occur whilst using the HTTP session.

       The ne_get_error function returns the current session error string. This string persists only until it is
       changed by a subsequent operation on the session. If localisation was enabled at build time, and if
       necessary enabled at run-time if necessary using ne_i18n_init, the returned string may have been
       translated into the user's current locale.

       The ne_set_error function can be used to set a new session error string, using a printf-style format
       string interface.

       Retrieve the current error string:

           ne_session *sess = ne_session_create(...);
           ...
           printf("Error was: %s\n", ne_get_error(sess));

       Set a new error string:

           ne_session *sess = ne_session_create(...);
           ...
           ne_set_error(sess, "Response missing header %s", "somestring");

ne_set_error returns a constant NUL-terminated string. In the default English locale, the returned string
       will not have a terminating “.”  period character.
