# NAME
curl_share_cleanup - close a shared object
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLSHcode curl_share_cleanup(CURLSH *share_handle);
~~~
# DESCRIPTION
This function deletes a shared object. The share handle cannot be used anymore
when this function has been called.
Passing in a NULL pointer in *share_handle* makes this function return
immediately with no action.
Any use of the **share_handle** after this function has been called and have
returned, is illegal.
# %PROTOCOLS%
# EXAMPLE
~~~c
int main(void)
{
CURLSHcode sh;
CURLSH *share = curl_share_init();
sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT);
/* use the share, then ... */
curl_share_cleanup(share);
}
~~~
# %AVAILABILITY%
# RETURN VALUE
CURLSHE_OK (zero) means that the option was set properly, non-zero means an
error occurred as *\<curl/curl.h\>* defines. See the libcurl-errors(3) man
page for the full list with descriptions. If an error occurs, then the share
object is not deleted.
