NAME

       curl_share_init - Create a shared object

SYNOPSIS

       #include <curl/curl.h>

       CURLSH *curl_share_init( );

DESCRIPTION

       This function returns a CURLSH handle to be used as input to all the other share-functions, sometimes referred to as a share handle in some
       places in the documentation. This init call MUST have a corresponding call to curl_share_cleanup when all operations using  the	share  are
       complete.

       This  share  handle is what you pass to curl using the CURLOPT_SHARE option with curl_easy_setopt(3), to make that specific curl handle use
       the data in this share.

RETURN VALUE

       If this function returns NULL, something went wrong (out of memory, etc.)  and therefore the share object was not created.

NAME

       libcurl-share - how to use the share interface

DESCRIPTION

       This  is an overview on how to use the libcurl share interface in your C programs. There are specific man pages for each function mentioned
       in here.

       All functions in the share interface are prefixed with curl_share.

OBJECTIVES

       The share interface was added to enable sharing of data between curl "handles".

ONE SET OF DATA - MANY TRANSFERS
       You can have multiple easy handles share data between them. Have them update and use the same cookie database or DNS cache! This way,  each
       single transfer will take advantage from data updates made by the other transfer(s).

SHARE OBJECT

       You create a shared object with curl_share_init(3). It returns a handle for a newly created one.

       You tell the shared object what data you want it to share by using curl_share_setopt(3).

       Since you can use this share from multiple threads, and libcurl has no internal thread synchronization, you must provide mutex callbacks if
       you're using this multi-threaded. You set lock and unlock functions with curl_share_setopt(3) too.

       Then, you make an easy handle to use this share, you set the CURLOPT_SHARE option with curl_easy_setopt(3), and pass in share  handle.  You
       can make any number of easy handles share the same share handle.

       To  make an easy handle stop using that particular share, you set CURLOPT_SHARE to NULL for that easy handle. To make a handle stop sharing
       a particular data, you can CURLSHOPT_UNSHARE it.

       When you're done using the share, make sure that no easy handle is still using it, and call curl_share_cleanup(3) on the handle.
