+# NAME
+
+CURLSHOPT_UNLOCKFUNC - mutex unlock callback
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+void unlockcb(CURL *handle, curl_lock_data data, void *clientp);
+
+CURLSHcode curl_share_setopt(CURLSH *share, CURLSHOPT_UNLOCKFUNC, unlockcb);
+~~~
+
+# DESCRIPTION
+
+Set a mutex unlock callback for the share object. There is a corresponding
+CURLSHOPT_LOCKFUNC(3) callback called when the mutex is first locked.
+
+The *unlockcb* argument must be a pointer to a function matching the
+prototype shown above. The arguments to the callback are:
+
+*handle* is the currently active easy handle in use when the share object
+is released.
+
+The *data* argument tells what kind of data libcurl wants to unlock. Make
+sure that the callback uses a different lock for each kind of data.
+
+*clientp* is the private pointer you set with CURLSHOPT_USERDATA(3).
+This pointer is not used by libcurl itself.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+extern void mutex_unlock(CURL *, curl_lock_data, void *);
+
+int main(void)
+{
+  CURLSHcode sh;
+  CURLSH *share = curl_share_init();
+  sh = curl_share_setopt(share, CURLSHOPT_UNLOCKFUNC, mutex_unlock);
+  if(sh)
+    printf("Error: %s\n", curl_share_strerror(sh));
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+CURLSHE_OK (zero) means that the option was set properly, non-zero means an
+error occurred. See libcurl-errors(3) for the full list with
+descriptions.
