Where can I find the code about the funs 'neg'?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~``
tmp > neg ( const tmp > & )


tmp > neg ( const GeometricField & )


void neg ( GeometricField & Res,
const GeometricField & sf
)


tmp neg ( const tmp & )


tmp neg ( const UList & )


void neg ( scalarField & Res,
const UList & sf
)


tmp > neg ( const tmp > & )


tmp > neg ( const FieldField & )


void neg ( FieldField & Res,
const FieldField & sf
)


dimensionedScalar neg ( const dimensionedScalar & )

I would either use the Doxygen documentation or go to $FOAM_SRC and 'grep' for it in */lnInclude/*.H.

(all the libraries have an lnInclude directory where all the files are linked to)
