.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);
|

.SH DESCRIPTION
|
|
Set the \fIoption\fP to \fIparameter\fP for the given \fIshare\fP.
|
|
.SH OPTIONS
|
|
.IP CURLSHOPT_LOCKFUNC
|
|
The \fIparameter\fP 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);
|
|
|
|
\fIdata\fP 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.
|
|
|
|
\fIaccess\fP defines what access type libcurl wants, shared or single.
|
|
|
|
\fIuserptr\fP is the pointer you set with \fICURLSHOPT_USERDATA\fP.
|
|
.IP CURLSHOPT_UNLOCKFUNC
|
|
The \fIparameter\fP must be a pointer to a function matching the following
|
|
prototype:
|
|
|
|
void unlock_function(CURL *handle, curl_lock_data data, void *userptr);
|
|
|
|
\fIdata\fP 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.
|
|
|
|
\fIuserptr\fP is the pointer you set with \fICURLSHOPT_USERDATA\fP.
|
|
.IP CURLSHOPT_SHARE
|
|
The \fIparameter\fP 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_SHARE\fP. It specifies that
|
|
the specified \fIparameter\fP will no longer be shared. Valid values are
|
|
the same as those for \fICURLSHOPT_SHARE\fP.
|
|
.IP CURLSHOPT_USERDATA
|
|
The \fIparameter\fP 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.3\fP
|
|
man page for the full list with descriptions.
