/*
** A Note About Memory Allocation:
**
** This driver uses malloc()/free() directly rather than going through
** the SQLite-wrappers sqlite3_malloc()/sqlite3_free(). Those wrappers
** are designed for use on embedded systems where memory is scarce and
** malloc failures happen frequently. Win32 does not typically run on
** embedded systems, and when it does the developers normally have bigger
** problems to worry about than running out of memory. So there is not
** a compelling need to use the wrappers.
**
** But there is a good reason to not use the wrappers. If we use the
** wrappers then we will get simulated malloc() failures within this
** driver. And that causes all kinds of problems for our tests. We
** could enhance SQLite to deal with simulated malloc failures within
** the OS driver, but the code to deal with those failure would not
** be exercised on Linux (which does not need to malloc() in the driver)
** and so we would have difficulty writing coverage tests for that
** code. Better to leave the code out, we think.
**
** The point of this discussion is as follows: When creating a new
** OS layer for an embedded system, if you use this file as an example,
** avoid the use of malloc()/free(). Those routines work ok on Windows
** desktops but not so well in embedded systems.
