easy:Pause(bitmask)
A connection can be paused by using this function or by letting the read or the write callbacks return
the proper magic return code (#CURL_READFUNC_PAUSE
and #CURL_WRITEFUNC_PAUSE
). A write callback that
returns pause signals to the library that it couldn't take care of any data at all, and that data will
then be delivered again to the callback when the writing is later unpaused.
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 (#CURLOPT_PROGRESSFUNCTION
), 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.
The bitmask
argument is a get of bits that sets the new state of the connection. The following bits can be used:
#CURLPAUSE_RECV
#CURLOPT_WRITEFUNCTION
) won't be called.
#CURLPAUSE_SEND
#CURLOPT_READFUNCTION
) won't be called.
#CURLPAUSE_ALL
#CURLPAUSE_CONT
