      NAME
           cxref - generate C program cross reference

      SYNTAX
           cxref [ options ] files

      DESCRIPTION
           Cxref analyzes a collection of C files and attempts to build
           a cross reference table.  Cxref utilizes a special version
           of cpp to include #define'd information in its symbol table.
           It produces a listing on standard output of all symbols
           (auto, static, and global) in each file separately, or with
           the -c option, in combination.  Each symbol contains an
           asterisk (*) before the declaring reference.

           In addition to the -D, -I and -U options (which are
           identical to their interpretation by rc(1)), the following
           options are interpreted by cxref:

           -c      Print a combined cross-reference of all input files.

           -w<num> Width option which formats output no wider than
                   <num> (decimal) columns.  This option will default
                   to 80 if <num> is not specified or is less than 51.

           -o file Direct output to named file.

           -s      Operate silently; does not print input file names.

           -t      Format listing for 80-column width.

      FILES
           /usr/lib/xcpp    special version of C-preprocessor.

      SEE ALSO
           rc(1).

      DIAGNOSTICS
           Error messages are unusually cryptic, but usually mean that
           you can't compile these files, anyway.
