/****************************************************************************** ** This file is an amalgamation of many separate C source files from SQLite ** version 3.5.8. By combining all the individual C code files into this ** single large file, the entire code can be compiled as a one translation ** unit. This allows many compilers to do optimizations that would not be ** possible if the files were compiled separately. Performance improvements ** of 5% are more are commonly seen when SQLite is compiled as a single ** translation unit. ** ** This file is all you need to compile SQLite. To use SQLite in other ** programs, you need this file and the "sqlite3.h" header file that defines ** the programming interface to the SQLite library. (If you do not have ** the "sqlite3.h" header file at hand, you will find a copy in the first ** 5642 lines past this header comment.) Additional code files may be ** needed if you want a wrapper to interface SQLite with your choice of ** programming language. The code for the "sqlite3" command-line shell ** is also in a separate file. This file contains only code for the core ** SQLite library. ** ** This amalgamation was generated on 2008-04-16 15:43:25 UTC. */ #define SQLITE_CORE 1 #define SQLITE_AMALGAMATION 1 #ifndef SQLITE_PRIVATE # define SQLITE_PRIVATE static #endif #ifndef SQLITE_API # define SQLITE_API #endif /************** Begin file sqliteInt.h ***************************************/ /* ** 2001 September 15 ** ** The author disclaims copyright to this source code.
