SQLITE3_VFS_FIND(3)        Library Functions Manual        SQLITE3_VFS_FIND(3)

NAME
     sqlite3_vfs_find, sqlite3_vfs_register, sqlite3_vfs_unregister - Virtual
     File System Objects

SYNOPSIS
     sqlite3_vfs *
     sqlite3_vfs_find(const char *zVfsName);

     int
     sqlite3_vfs_register(sqlite3_vfs*, int makeDflt);

     int
     sqlite3_vfs_unregister(sqlite3_vfs*);

DESCRIPTION
     A virtual filesystem (VFS) is an sqlite3_vfs object that SQLite uses to
     interact with the underlying operating system.  Most SQLite builds come
     with a single default VFS that is appropriate for the host computer.  New
     VFSes can be registered and existing VFSes can be unregistered.  The
     following interfaces are provided.

     The sqlite3_vfs_find() interface returns a pointer to a VFS given its
     name.  Names are case sensitive.  Names are zero-terminated UTF-8
     strings.  If there is no match, a NULL pointer is returned.  If zVfsName
     is NULL then the default VFS is returned.

     New VFSes are registered with sqlite3_vfs_register().  Each new VFS
     becomes the default VFS if the makeDflt flag is set.  The same VFS can be
     registered multiple times without injury.  To make an existing VFS into
     the default VFS, register it again with the makeDflt flag set.  If two
     different VFSes with the same name are registered, the behavior is
     undefined.  If a VFS is registered with a name that is NULL or an empty
     string, then the behavior is undefined.

     Unregister a VFS with the sqlite3_vfs_unregister() interface.  If the
     default VFS is unregistered, another VFS is chosen as the default.  The
     choice for the new VFS is arbitrary.
