保存到磁盘的内存数据库。-Savingtodiskanin-memorydatabase

I made a database through sqlite in c++.

我用c++通过sqlite创建了一个数据库。

The db has been created in memory (using the ":memory:" parameter insted of a filename), in order to have a very quick behavior.

db已经在内存中创建(使用“:内存:”一个文件名的参数)，以便有一个非常快的行为。

The database is created by the following lines:

数据库由以下几行创建:

sqlite3* mem_database;
if((SQLITE_OK == sqlite3_open(":memory:", &mem_database)){
    // The db has been correctly created and
    // I can do some stuff with it.
}
sqlite3_close(mem_database);

My problem is: how can I write the in-memory database to disk? (through c/c++ of course).

我的问题是:如何将内存数据库写入磁盘?(当然通过c / c++)。

I read something about the ATTACH and DETACH sqlite commands, but I can get them working only with the sqlite interactive shell (not from c/c++ code).

我读了一些关于ATTACH和DETACH sqlite命令的东西，但是我可以让它们只使用sqlite交互式shell(而不是c/c++代码)。
