*************************************************************************
**
** The code in this file runs a few multi-threaded test cases using the
** SQLite library. It can be compiled to an executable on unix using the
** following command:
**
**   gcc -O2 threadtest3.c sqlite3.c -ldl -lpthread -lm
**
** Even though threadtest3.c is the only C source code file mentioned on
** the compiler command-line, #include macros are used to pull in additional

** C code files named "tt3_*.c".
**
** After compiling, run this program with an optional argument telling
** which test to run.  All tests are run if no argument is given.  The
** argument can be a glob pattern to match multiple tests.  Examples:
**

**        ./a.out                 -- Run all tests
**        ./a.out walthread3      -- Run the "walthread3" test


**        ./a.out 'wal*'          -- Run all of the wal* tests

**        ./a.out --help          -- List all available tests
**

** The exit status is non-zero if any test fails.
