NAME
       curl_share_setopt - Set options for a shared object

SYNOPSIS
       #include 

       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 lick 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.

       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  CURL-
              SHOPT_SHARE.

       CURLSHOPT_USERDATA
              The  parameter  allows  you  to  specify  a pointer to data that will 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    defines.  See  the  libcurl-errors.3  man  page  for the full list with
       descriptions.
