| 5 ** following command: | |
| 6 ** | |
| 7 ** gcc -O2 threadtest3.c sqlite3.c -ldl -lpthread -lm | |
| 8 ** | |
| 9 ** Then run the compiled program. The exit status is non-zero if any tests | |
| 10 ** failed (hopefully there is also some output to stdout to clarify what went | |
| 11 ** wrong). | |
| 12 ** | |
| 13 ** There are three parts to the code in this file, in the following order: | |
| 14 ** | |
| 15 ** 1. Code for the SQL aggregate function md5sum() copied from | |
| 16 ** tclsqlite.c in the SQLite distribution. The names of all the | |
| 17 ** types and functions in this section begin with "MD5" or "md5". | |
| 18 ** | |
| 19 ** 2. A set of utility functions that may be used to implement | |
| 20 ** multi-threaded test cases. These are all called by test code | |
| 21 ** via macros that help with error reporting. The macros are defined | |
| 22 ** immediately below this comment. | |
| 23 ** | |
| 24 ** 3. The test code itself. And a main() routine to drive the test | |
