How to solve the memory leak question when use the libcurl?
in my main i have in line 33 the call

curl_global_init(CURL_GLOBAL_ALL);

at end of code i have the call:
curl_global_cleanup();

But this not solve the problem, how i can remove all memory leak?

16 still reachable are when i use the libcurl, 1 is another lib.

This is part of my output from valgrind:
