- .SH NAME
- curl_share_setopt - Set options for a shared object
- .SH SYNOPSIS
- .B #include <curl/curl.h>
- .sp
- CURLSHcode curl_share_setopt(CURLSH *share, CURLSHoption option, parameter);
- .ad
- .SH DESCRIPTION
- Set the fIoptionfP to fIparameterfP for the given fIsharefP.
- .SH OPTIONS
- .IP CURLSHOPT_LOCKFUNC
- The fIparameterfP 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);
- fIdatafP 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.
- fIaccessfP defines what access type libcurl wants, shared or single.
- fIuserptrfP is the pointer you set with fICURLSHOPT_USERDATAfP.
- .IP CURLSHOPT_UNLOCKFUNC
- The fIparameterfP must be a pointer to a function matching the following
- prototype:
- void unlock_function(CURL *handle, curl_lock_data data, void *userptr);
- fIdatafP 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.
- fIuserptrfP is the pointer you set with fICURLSHOPT_USERDATAfP.
- .IP CURLSHOPT_SHARE
- The fIparameterfP specifies a type of data that should be shared. This may
- be set to one of the values described below.
- .RS
- .IP CURL_LOCK_DATA_COOKIE
- Cookie data will be shared across the easy handles using this shared object.
- .IP 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!
- .RE
- .IP CURLSHOPT_UNSHARE
- This option does the opposite of fICURLSHOPT_SHAREfP. It specifies that
- the specified fIparameterfP will no longer be shared. Valid values are
- the same as those for fICURLSHOPT_SHAREfP.
- .IP CURLSHOPT_USERDATA
- The fIparameterfP allows you to specify a pointer to data that will be passed
- to the lock_function and unlock_function each time it is called.
- .SH RETURN VALUE
- CURLSHE_OK (zero) means that the option was set properly, non-zero means an
- error occurred as fI<curl/curl.h>fP defines. See the fIlibcurl-errors.3fP
- man page for the full list with descriptions.
