c - how to get cookies id from HTTP header using libcurl -

the http haeder of server :

server: apache-coyote/1.1 set-cookie: jsessionid=72d8dc23bd37016cd5557bb353dd008e; path=/tt/; httponly soapaction:  content-type: text/xml;charset=iso-8859-1 content-length: 491 date: wed, 03 jun 2015 14:02:53 gmt 

how cookies id "jsessionid=72d8dc23bd37016cd5557bb353dd008e" , using http client.

i used these functions init http header , send msg :

to set cookies option http client doesn't take cookies id http header of server communication between client , server broken

any appreciated
