Name
       cxref - generate C program cross reference

Syntax
       cxref [options] files

Description
       The  command  analyzes a collection of C files and attempts to build a cross reference table.  The command utilizes a special version of 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.

Options
       -c	 Prints a combined cross-reference of all input files.

       -Dname	 Defines name to processor, as if by #define.  Default value is 1.

       -Idir	 Searches named directory for files whose names do not begin with a backslash (/).

       -o file	 Directs output to named file.

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

       -t	 Formats listing for 80-column width.

       -Uname	 Removes any initial definition of name.

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

Diagnostics
       Error messages usually indicate a problem that will prevent the file from compiling.

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

NAME

       cxref-cpp - A modified C preprocessor to use with cxref.

SYNOPSIS

       cxref-cpp ...

DESCRIPTION

       To  improve  the  output  that  is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied
       (named cxref-cpp).

       This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler.	In
       a  standard  preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is
       not important.

       With cxref-cpp, there are some features that are different to the standard GNU CPP:

	      Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include  lines  from  the  source
	      file.  In version 2.8.0 and later this option is present.

	      Comments	trailing  a  #include  or  a  #define are not preserved by all versions of gcc even if the -C option is used.  This is not
	      important while compiling, but is useful for documenting.

	      The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed.  This
	      means  that it includes the same default include directory paths and macro definitions.  The file that contains these definitions is
	      called cxref-cpp.defines and is installed by the cxref-cpp-configure program or specified by  the  -cxref-cpp-defines  command  line
	      option.

OPTIONS

       The same as for gcc, apart from '-cxref-cpp-defines' described above.
