** CAPI3REF: Initialize The SQLite Library
**
** ^The sqlite3BtreeInitialize() routine initializes the
** SQLite library. ^The sqlite3BtreeShutdown() routine
** deallocates any resources that were allocated by sqlite3BtreeInitialize().
** These routines are designed to aid in process initialization and
** shutdown on embedded systems. Workstation applications using
** SQLite normally do not need to invoke either of these routines.
**
** A call to sqlite3BtreeInitialize() is an "effective" call if it is
** the first time sqlite3BtreeInitialize() is invoked during the lifetime of
** the process, or if it is the first time sqlite3BtreeInitialize() is invoked
** following a call to sqlite3BtreeShutdown(). ^(Only an effective call
** of sqlite3BtreeInitialize() does any initialization. All other calls
** are harmless no-ops.)^
**
** A call to sqlite3BtreeShutdown() is an "effective" call if it is the first
** call to sqlite3BtreeShutdown() since the last sqlite3BtreeInitialize(). ^(Only
** an effective call to sqlite3BtreeShutdown() does any deinitialization.
** All other valid calls to sqlite3BtreeShutdown() are harmless no-ops.)^
**
** The sqlite3BtreeInitialize() interface is threadsafe, but sqlite3BtreeShutdown()
** is not. The sqlite3BtreeShutdown() interface must only be called from a
** single thread. All open [database connections] must be closed and all
** other SQLite resources must be deallocated prior to invoking
** sqlite3BtreeShutdown().
**
** Among other things, ^sqlite3BtreeInitialize() will invoke
** sqlite3_os_init(). Similarly, ^sqlite3BtreeShutdown()
** will invoke sqlite3_os_end().
**
** ^The sqlite3BtreeInitialize() routine returns [SQLITE_OK] on success.
** ^If for some reason, sqlite3BtreeInitialize() is unable to initialize
** the library (perhaps it is unable to allocate a needed resource such
** as a mutex) it returns an [error code] other than [SQLITE_OK].
**
** ^The sqlite3BtreeInitialize() routine is called internally by many other
** SQLite interfaces so that an application usually does not need to
** invoke sqlite3BtreeInitialize() directly. For example, [sqlite3_open()]
** calls sqlite3BtreeInitialize() so the SQLite library will be automatically
** initialized when [sqlite3_open()] is called if it has not be initialized
** already. ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
** compile-time option, then the automatic calls to sqlite3BtreeInitialize()
** are omitted and the application must call sqlite3BtreeInitialize() directly
** prior to using any other SQLite interface. For maximum portability,
** it is recommended that applications always invoke sqlite3BtreeInitialize()
** directly prior to using any other SQLite interface. Future releases
** of SQLite may require this. In other words, the behavior exhibited
** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
** default behavior in some future release of SQLite.
**
** The sqlite3_os_init() routine does operating-system specific
** initialization of the SQLite library. The sqlite3_os_end()
** routine undoes the effect of sqlite3_os_init(). Typical tasks
** performed by these routines include allocation or deallocation
** of static resources, initialization of global variables,
** setting up a default [sqlite3_vfs] module, or setting up
** a default configuration using [sqlite3_config()].
**
** The application should never invoke either sqlite3_os_init()
** or sqlite3_os_end() directly. The application should only invoke
** sqlite3BtreeInitialize() and sqlite3BtreeShutdown(). The sqlite3_os_init()
** interface is called automatically by sqlite3BtreeInitialize() and
** sqlite3_os_end() is called by sqlite3BtreeShutdown(). Appropriate
** implementations for sqlite3_os_init() and sqlite3_os_end()
** are built into SQLite when it is compiled for Unix, Windows, or OS/2.
** When [custom builds | built for other platforms]
** (using the [SQLITE_OS_OTHER=1] compile-time
** option) the application must supply a suitable implementation for
** sqlite3_os_init() and sqlite3_os_end(). An application-supplied
** implementation of sqlite3_os_init() or sqlite3_os_end()
** must return [SQLITE_OK] on success and some other [error code] upon
** failure.
