FCS makes a clear distinction between the internals of the
program, that are subject to change from version to version,
and between the interface supplied to the user or the
application programmer. All the modules starting from
instance.c
and below are the internals of
the program.
lib.c
contains the API functions used by
the programmer. cmd_line.c
is an API to
analyse a Freecell Solver command line. It itself uses only the
lib.c
API. It provides a more flexible
interface for configuring Freecell Solver, even to the application
programmer.
main.c
,
test_multi_parallel.c
,
threaded_range_solver.c
,
and fc_pro_range_solver.c
are command line programs that use the command line interface
and programmers interface. Others can be written (and have
been written).
