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.
