curl_share_cleanup(3) Library Functions Manual curl_share_cleanup(3)

curl_share_cleanup - close a shared object

#include <curl/curl.h>
CURLSHcode curl_share_cleanup(CURLSH *share_handle);

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.

This functionality affects all supported protocols

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);
}

Added in curl 7.10

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.
