Database.Sqlite3.Low
Description
This is intended to be a low level wrapper over sqlite3 library. These design decisions guide this module:
- Portability.
- It is meant to be as close as possible to a bijection over sqlite3 objects, constants and functions. The original documentation for any sqlite3 name should be sufficient to understand its wrapper.
- Everything not UTF-8 has been removed in favor of UTF-8.
-
sqlite3_prefix has been removed from all object and function names since it can be mapped to a qualified module import. - Mutex related names are not wrapped, as they would just duplicate existing functionality.
- All sqlite3 experimental or obsolete code (marked with
exporobsin the official documentation) has not been wrapped, as well as the testing interface (sqlite3_test_controland related constants). - Preprocessor constant definitions have been replaced by equal values. All were typed to CInt, except for SQLITE_STATIC and SQLITE_TRANSIENT (mapped to sqliteStatic and sqliteTransient) which were typed as function pointers as faithfully as possible to the underline C code. Version information constants are not mapped for portability, and the user can always call the mappings of sqlite3_libversion and sqlite3_libversion_number functions instead.
