I tried using n_dotsql() to fire a single sql statement. Actually I got an error (missing and so the buffer in se->f->buf got filled. Anyway n_dotsql reported 0 as no error condition. How to access the error message in se->f->buf ? I only saw the putmsg thing which are not adaptable as I do not have a UI.

Putmsg doesn't require any kind of ui. You may do whatever you wish with the messages you intercept with your own putmsg() function. See

Isn't there just only a function to check if there is an error and then access the error-text ?

Not really. You can create one by writing a putmsg that will store the message for later retrieval.
