* This program tries to be as small as possible itself, to
* avoid perturbing the system memory utilization with its
* own execution. It also attempts to have as few dependencies

* It uses no library calls, and only the following 3 syscalls:

Original RAWVF2RAWVF program by Maksim Bashov 2013-07-29. The program notes warned
"the following code is much more awful than you may expect".
Program was modified by Zhou Ke (crazyks) 2014-04-18. This fixed 2 bugs in the valeq()
function relating to incrementing a count. It also fixed a bug where the len variable
was called while being defined so results were off by 1 byte.
Modified by Damien Moore for a month ending 2020-02-09. Changes included:
- Fixed bug where error check failed due to differences between Linux and Windows.
- Fix bug with number events so cell co-ordinates always start from 1 instead of 0.
- Fixed bug where check_win() printed to screen instead of selected output method.
- Fixed bug where check_win() was not called after openings.
- Fixed bug where qm was checked instead of !qm.
- Removed claims_win variable as the updated Viennasweeper parser makes this redundant.
- Renamed variables to remove confusion over hun and ths in score calculations.
- Truncated decimals in various calculations instead of rounding.
- Aligned event names to RAWVF version 5 standard and removed unused functionality.
- Changed function order so now functions are logically grouped.
- Added detailed comments throughout file.
Program was modified by Enbin Hu (Flop) 2021-06-13. Fix the bug of not handling the
question mark setting toggle.
This is being released as Rawparser version 6.
Program works for Minesweeper Clone, Minesweeper Arbiter, Minesweeper X and Viennasweeper
in both legal and cheat modes.
The standard legal moves are LC (left click), LR (left release), RC (right click), RR
(right release), MC (middle press) and MR (middle press). Flags and Questionmarks are
placed and removed with a RC. The timer starts after the first cell is opened. Cells
open after a LC-LR sequence. A Chord is when you LC and RC (in any order) then LR and
RR (at the same time or in that order) on an open cell. If the cell contains a number
and touches the same number of flags additional cells touched are opened. The normal
chording method is to flag (RC-RR) then chord (LC-RC-LR-RR) in two motions. You can also
chord by holding SHIFT during a LC-LR. You can also chord with a MC-MR. A fourth method
is to flag (RC) then slide onto a number to finish the chord (LC-LR-RR) in one motion
known as a 1.5 Click.
Arbiter 0.44 and earlier allow an illegal move known as a Rilian Click. This occurs when
a chord is released on an unopened cell (instead of a number) and the LR occurs after the
RR. In legal game play this is a failed chord and nothing happens but a Rilian Click will
perform a left click and open the cell. When running this program use the -r option to
process these correctly.
Elmar Technique is possible in all official minesweeper versions. This occurs when the left
mouse button is configured to left click on both press and release. The code in this program
will process but not identify Elmar Technique (the variable must be set in the minesweeper
program parser and passed to this program in the input file).
Program also has code to process FreeSweeper cheat options such as Nono (where holding SHIFT
and LC lets you flag multiple cells by dragging the mouse over the cells like in Nonosweeper),
Superflag (where RC on a number will flag adjacent cells if their count is the same) and
Superclick (where LC on a number does a chord). The code in this program does not change the
value of these variables and depends on the underlying minesweeper program parser to include
these variables in their output.

* FILE: mpithreads_threads.c
* DESCRIPTION:
* This simple program illustrates the use of Pthreads in a program obtained
* by modifying a serial code that performs a dot product. It is the second
* of four codes used to show the progression from a serial program to a
* hybrid MPI/Pthreads program. The other relevant codes are:
* - mpithreads_serial.c - The serial version
* - mpithreads_mpi.c - A distributed memory programming model with MPI
* - mpithreads_both.c - A hybrid model that utilizes both MPI and
* Pthreads to execute on systems that are comprised of clusters
* of SMP's.
* The main data is made available to all threads through a globally
* accessible structure. Each thread works on a different part of the
* data. The main thread waits for all the threads to complete their
* computations, and then it prints the resulting sum.
