Re: Usage of curl_easy_pause

Hi,

I am attaching a sample program I have written to show usage of the
curl_easy_pause() API in my code. This sample program is not working as
expected. Please let me know if the usage of the API in my program is
correct or wrong. The *current output of the program* is below:*---- paused
the curl handle for perform *
*---- added the timer for 1sec *
*---- came to curl header callback *
*---- came to curl callback with data: *
*---- added the timer for 1sec again*
*---- added the timer for 1sec again*
*---- added the timer for 1sec again*
*---- continued the curl handle for perform *

The *output that I am looking* for should be something like below:
*---- paused the curl handle for perform *
*---- added the timer for 1sec *
*---- added the timer for 1sec again*
*---- added the timer for 1sec again*
*---- added the timer for 1sec again*
*---- continued the curl handle for perform *
*---- came to curl header callback *
*---- came to curl callback with data: *

Thanks in advance,
Ravi
