</span>The callback given to pa_stream_update_timing_info() has type<br>
pa_context_success_cb_t, which has the "success" argument. If "success"<br>
is false, you can get the error code with pa_context_errno(). If the<br>
operation failed due to a timeout, the error code should be<br>
PA_ERR_TIMEOUT.<br></blockquote><div><br></div><div>Thank you, I did the change, and so far only got timeouts.<br></div><div>Good news!<br><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">
</span>I don't know (or remember) the reason. I would guess that it has to do<br>
with maintaining a stable public API and avoiding unnecessary complexity<br>
