  cxref	- Creates a C program cross-reference listing


  cxref	[-cFlstV] [-o file] [-w	[number] | [-L cols] ] [-D name[=def]]... [-I
  dir]... [-U name]... [-Ndnumber] [-Nlnumber] [-Nnnumber] [-Ntnumber]

  The token -- (double-dash) is	accepted as a delimiter	indicating the end of
  options.  Any	following arguments are	treated	as operands, even if they
  begin	with the - character.


  Interfaces documented	on this	reference page conform to industry standards
  as follows:

  cxref: XCU5.0

  Refer	to the standards(5) reference page for more information	about indus-
  try standards	and associated tags.


  The following	options	are included in	XCU5.0:

  -c  Displays a combined listing of the cross-references in all input files.

  -D name[=def]
      Defines name, as if by a C-language #define directive. If	no =def	is
      given, a value of	1 is used.

  -I dir
      Adds the directory specified by dir to the list of directories in	which
      the lint program searches	for #include files.

  -o file
      Directs the output to the	specified file.

  -s  Does not display the input filenames.

  -U name
      Removes any initial definition of	name, where name is a reserved symbol
      that is predefined by the	particular preprocessor.

  -w [number]
      Formats the output no wider than number (decimal)	columns.  This option
      defaults to 80 if	number is unspecified or is less than 51.

  The following	options	are not	included in XCU5.0. They are included in a
  System V specification or are	proprietary.

  -F  [Tru64 UNIX]  Prints the full path of the	referenced file	names.	By
      default, only the	last component of the full path	is printed.

  -L cols
      [Tru64 UNIX]  Specifies the maximum number of columns that can be
      printed in the LINE field	to the cols argument.  The default is five
      columns for this field.

  -l  [Tru64 UNIX]  Suppresses printing	of local variables.  Only global
      variables	and file scope statistics are printed.

      [Tru64 UNIX]  Changes the	dimension table	size to	number.	 The default
      is 2000.

      [Tru64 UNIX]  Changes the	number of type nodes to	number.	 The default
      is 8000.

      [Tru64 UNIX]  Changes the	symbol table size to number.  The default is

      [Tru64 UNIX]  Changes the	number of tree nodes to	number.	 The default
      is 1000.

  -t  [Tru64 UNIX]  Makes the listing 80 bytes wide.

  -V  [SVID3]  Prints the version number information for the cxref command to
      standard error.


  The cxref command analyzes C program files and creates a cross-reference
  table, using a version of the	cpp macro preprocessor to include #define
  directives in	its symbol table.

  The cxref command writes to standard output a	listing	of all symbols in
  each file processed, either separately or in combination (see	the -c

  [Tru64 UNIX]	Function prototypes are	handled	in a special way: for an
  old-style function declaration, the function prototype name is listed, but
  the optional prototype identifiers are not. The formal parameters in a
  function definition are always listed, whether or not	the prototype is an
  old-style function definition.  When a reference to a	symbol is that
  symbol's declaration,	an asterisk (*)	precedes it.


  To provide a combined	cross-reference	listing	of stdin1.c and	stdin2.c,
  making the output 60 columns wide, enter:

       cxref -c	-w 60 stdin1.c stdin2.c	>> output


  The following	environment variables affect the behavior of cxref:

      Provides a default value for the locale category variables that are not
      set or null.

      If set, overrides	the values of all other	locale variables.

      Determines the order in which output is sorted for the -x	option.

      Determines the locale for	the interpretation of byte sequences as	char-
      acters (single-byte or multibyte)	in input parameters and	files.

      Determines the locale used to affect the format and contents of diag-
      nostic messages displayed	by the command.

      Determines the location of message catalogs for processing of


      Special version of C preprocessor.
