The C preprocessor expects two file names as arguments, @var{infile} and
@var{outfile}. The preprocessor reads @var{infile} together with any other
files it specifies with @samp{#include}. All the output generated by the
combined input files is written in @var{outfile}.
Either @var{infile} or @var{outfile} may be @samp{-}, which as @var{infile}
means to read from standard input and as @var{outfile} means to write to
standard output. Also, if @var{outfile} or both file names are omitted,
the standard output and standard input are used for the omitted file names.
Either @var{infile} or @var{outfile} may be @samp{-}, which as
@var{infile} means to read from standard input and as @var{outfile}
