XBMC is a well-known open-source media center and home theater computer software. It has been translated into over 30 languages. At the same time, its functions are highly scalable through third-party plug-ins and extensions, supporting PVR (personal video recorders ).
Since XBMC 14, the open source software will be renamed as

.$table->dropIndex(‘geo_state_index‘);Drop a basic index from the "Geo" table.Foreign Key ConstraintsLaravel also provides support for creating foreign key constraints, which is used to force referential integrity at the D Atabase level. For example, let's define a column on the user_id posts table that references the id column on a users table:Schema::table(‘posts‘, function ($table) { $table->integer(‘user_id‘)->unsigned(); $table->foreign(‘user_id‘)->references(‘id‘)->on(‘users‘);});Als

It is such a simple three-sentence code that prevents the content of one. h from being repeatedly included.
In this case, in Main. C:

The two have a common name, raiI object. To prevent resource leakage, use the raiI object. They obtain resources in the constructor and release resources in the destructor. Generally, shared_ptr is selected because its replication behavior is normal and intuitive. The auto_ptr copy action points to null.
In addition, tr1: shared_ptr allows you to create a resource release function when the smart pointer is set up (the

1. coroutine (microthread)Coroutine is a lightweight thread in user mode.Coroutine has its own register context and stack. During the coroutine scheduling switch, the register context and stack are saved to other places. When the switch is back, the previously saved register context and stack are restored. Therefore:

program is determined by an external event. It is characterized by the inclusion of an event loop that uses a callback mechanism to trigger the corresponding processing when an external event occurs. Two other common programming paradigms are (single-threaded) synchronization and multithreaded programming.8. Cache I/OCache I/O is also known as standard I/O, and most file system default I/O operations are cache I/O. In the Linux cache I/O mechanism, the operating system caches the I/O data in th
