using sqlite3_busy_timeout() in Qt

[ahmetturan]

I set database:

QsqlDatabase db;
db = QsqlDatabase::addDatabase("QSQLITE");

QsqlDatabase db;
db = QsqlDatabase::addDatabase("QSQLITE");

To copy to clipboard, switch view to plain text mode 

But I can not find how can I use sqlite3_busy_timeout(sqlite3*, int ms) function in Qt.

@anda_skoa thank you for your answer but I do not undestand how can I use the function?
handle () gives me sqlite3 object but how can I use the sqlite3_busy_timeout() function?
can you give an example?

Not sure what you need an example for, the function seems to be quite simple to call

QVariant v = db.driver()->handle();
 if (v.isValid() && qstrcmp(v.typeName(), "sqlite3*") == 0) {
     // v.data() returns a pointer to the handle
     sqlite3 *handle = *static_cast<sqlite3 **>(v.data());
     if (handle != 0) { // check that it is not NULL
 
         sqlite3_busy_timeout(handle, 100);
 
     }
 }

QVariant v = db.driver()->handle();
 if (v.isValid() && qstrcmp(v.typeName(), "sqlite3*") == 0) {
     // v.data() returns a pointer to the handle
     sqlite3 *handle = *static_cast<sqlite3 **>(v.data());
     if (handle != 0) { // check that it is not NULL

         sqlite3_busy_timeout(handle, 100);

     }
 }
