curl_share_setopt(3)                           libcurl Manual                           curl_share_setopt(3)



NAME
       curl_share_setopt - Set options for a shared object

SYNOPSIS
       #include <curl/curl.h>

       CURLSHcode curl_share_setopt(CURLSH *share, CURLSHoption option, parameter);

DESCRIPTION
       Set the option to parameter for the given share.

OPTIONS
       CURLSHOPT_LOCKFUNC
              The parameter must be a pointer to a function matching the following prototype:

              void lock_function(CURL *handle, curl_lock_data data, curl_lock_access access, void *userptr);

              data defines what data libcurl wants to lock, and you must make sure that  only  one  lock  is
              given at any time for each kind of data.

              access defines what access type libcurl wants, shared or single.

              userptr is the pointer you set with CURLSHOPT_USERDATA.

       CURLSHOPT_UNLOCKFUNC
              The parameter must be a pointer to a function matching the following prototype:

              void unlock_function(CURL *handle, curl_lock_data data, void *userptr);

              data  defines  what data libcurl wants to unlock, and you must make sure that only one lock is
              given at any time for each kind of data.

              userptr is the pointer you set with CURLSHOPT_USERDATA.

       CURLSHOPT_SHARE
              The parameter specifies a type of data that should be shared. This may be set to  one  of  the
              values described below.

              CURL_LOCK_DATA_COOKIE
                     Cookie data will be shared across the easy handles using this shared object.

              CURL_LOCK_DATA_DNS
                     Cached  DNS hosts will be shared across the easy handles using this shared object. Note
                     that when you use the multi interface, all easy handles added to the same multi  handle
                     will share DNS cache by default without this having to be used!

              CURL_LOCK_DATA_SSL_SESSION
                     SSL  session  IDs will be shared across the easy handles using this shared object. This
                     will reduce the time spent in the SSL handshake when reconnecting to the  same  server.
                     Note SSL session IDs are reused within the same easy handle by default.

       CURLSHOPT_UNSHARE
              This  option  does  the opposite of CURLSHOPT_SHARE. It specifies that the specified parameter
              will no longer be shared. Valid values are the same as those for CURLSHOPT_SHARE.

       CURLSHOPT_USERDATA
              The parameter allows you to specify a pointer to data that will be passed to the lock_function
              and unlock_function each time it is called.

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.
