SQLITE3_CREATE_MODULE(3)

NAME
sqlite3_create_module, sqlite3_create_module_v2 - Register A Virtual Table Implementation

SYNOPSIS
int
sqlite3_create_module(sqlite3 *db, const char *zName, const sqlite3_module *p, void *pClientData );
int
sqlite3_create_module_v2(sqlite3 *db, const char *zName, const sqlite3_module *p, void *pClientData, void(*xDestroy)(void*) );

DESCRIPTION
These routines are used to register a new virtual table module name. Module names must be registered before creating a new virtual table using the module and before using a preexisting virtual table for the module.

The module name is registered on the database connection specified by the first parameter. The name of the module is given by the second parameter. The third parameter is a pointer to the implementation of the virtual table module. The fourth parameter is an arbitrary client data pointer that is passed through into the xCreate and xConnect methods of the virtual table module when a new virtual table is be being created or reinitialized.

The sqlite3_create_module_v2() interface has a fifth parameter which is a pointer to a destructor for the pClientData. SQLite will invoke the destructor function (if it is not NULL) when SQLite no longer needs the pClientData pointer. The destructor will also be invoked if the call to sqlite3_create_module_v2() fails. The sqlite3_create_module() interface is equivalent to sqlite3_create_module_v2() with a NULL destructor.
