While it may feel tempting, take care and notice that you cannot call this
function from another thread. To unpause, you may for example call it from the
progress callback (see \fIcurl_easy_setopt(3)\fP's
\fICURLOPT_PROGRESSFUNCTION\fP), which gets called at least once per second,
even if the connection is paused.
When this function is called to unpause reading, the chance is high that you
will get your write callback called before this function returns.
