[Bug-gnubg] SGF code question

[Chris Wilson]

I'm trying to write a routine apart from gnubg that I can use to parse
the .SGF file so I can place the individual game info into a database.
However, one section has me a bit confused.  Take the following entry:

[M:22 21 22 22 0 0 0 0 1 0 21 22 0 0 0 0 0 0 0.120965 0.030241 0.000000 
0.000000]

This is created by the following code block:

if( psc->fMoves ) {
        fprintf( pf, "[M:%d %d %d %d ", 
        psc->anUnforcedMoves[ 0 ],
        psc->anUnforcedMoves[ 1 ],
        psc->anTotalMoves[ 0 ],
        psc->anTotalMoves[ 1 ] );
for( st = SKILL_VERYBAD; st <= SKILL_VERYGOOD; st++ )
        fprintf( pf, "%d %d ", psc->anMoves[ 0 ][ st ],
        psc->anMoves[ 1 ][ st ] );

        fprintf( pf, "%.6f %.6f %.6f %.6f]",
        psc->arErrorCheckerplay[ 0 ][ 0 ],
        psc->arErrorCheckerplay[ 0 ][ 1 ],
        psc->arErrorCheckerplay[ 1 ][ 0 ],
        psc->arErrorCheckerplay[ 1 ][ 1 ] );
}

1) Do these values alternate White/Black?
2) The For loop seems to generate 7 sets of values. What do
these values represent?

Many thanks,

Chris
