curl_share_init(3) libcurl Manual curl_share_init(3)NAME
curl_share_init - Create a shared object
CURLSH *curl_share_init( );
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
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.
If this function returns NULL, something went wrong (out of memory, etc.) and therefore the share object was not created.

libcurl-share - how to use the share interface
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
All functions in the share interface are prefixed with curl_share.
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).
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). Currently you can only share DNS and/or COOKIE
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.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
