NAME
     cxref - generate C program cross-reference

SYNOPSIS
     ccxxrreeff [[options]] files

DESCRIPTION
     The ccxxrreeff command analyzes  a  collection  of  C  files  and
     builds  a  cross-reference table.  ccxxrreeff uses a special ver-
     sion of cccc to include ##ddeeffiinnee'd information  in  its  symbol
     table.   It  generates  a list of all symbols (auto, static,
     and global) in each individual file, or, with the --cc option,
     in combination.  The table includes four fields: NAME, FILE,
     FUNCTION, and LINE. The line numbers appearing in  the  LINE
     field  also  show reference marks as appropriate. The refer-
     ence marks include:

          assignment     =
          declaration    -
          definition     *


     If no reference marks  appear,  you  can  assume  a  general
     reference.

OPTIONS
     ccxxrreeff interprets the --DD, --II, --UU options in the  same  manner
     that  cccc  does.  In addition, ccxxrreeff interprets the following
     options:

     --CC      Run only the first pass of  ccxxrreeff,  creating  a  ..ccxx
             file  that  can  later  be passed to ccxxrreeff.  This is
             similar to the --cc option of cccc or lliinntt.

     --cc      Combine the  source  files  into  a  single  report.
             Without  the  --cc  option, ccxxrreeff generates a separate
             report for each file on the command line.

     --dd      Disable printing  declarations,  making  the  report
             easier to read.

     --FF      Print the full path of the referenced file names.

     --LLcols  Modify the number of columns in the LINE field.   If
             you  do  not  specify  -L,  cxref  defaults  to five
             columns.

     --ll      Do not print local variables.  Print only global and
             file scope statistics.

     --oo file Direct output to file.

     -R      Include referenced functions in the  cross-reference
             list..

     --ss      Operate silently; do not print input file names.

     --tt      Format listing for 80-column width.

     --VV      Print version information on the standard error.

     --WWname,file, function, line
             Change the default width of at least one field.  The
             default widths are:
             Field       Characters

             NAME        15
             FILE        13
             FUNCTION    15
             LINE        20 (4 per column)


     --wwnum   Format output no wider than num  (decimal)  columns.
             If  -w  is not specified, or if num is less than 51,
             the width will default to 80 columns.

ENVIRONMENT
     TMPDIR    cxref writes temporary files to the directory  set
               by  this environmental variable.  If TMPDIR is not
               set,  cxref  uses   /var/tmp   [see   tempnam   in
               tmpnam(3S)].

FILES
     TTMMPPDDIIRR//ttccxx..**        temporary files

     TTMMPPDDIIRR//ccxx..**         temporary files

EXAMPLE
     a.c

     1    main()
     2    {
     3         int i;
     4         extern char c;
     5
     6         i=65;
     7         c=(char)i;
     8    }



     Resulting cross-reference table:

     NAME    FILE          FUNCTION    LINE

     c       a.c           ---         4-      7=
     i       a.c           main        3*      6=   7
     main    a.c           ---         2*

DIAGNOSTICS
     Error messages usually mean you cannot compile the files.
