AVAILABILITY
This command is available with the
System V
software installation option. Refer to
[a manual with the abbreviation INSTALL]
for information on how to install optional software.
DESCRIPTION
cxref
analyzes a collection of C files
and attempts to build a cross-reference table.
cxref
utilizes a special option of
cpp.1
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.
SYSTEM V DESCRIPTION
The System V version of
cxref,
run as
/usr/5bin/cxref,
makes the
C
preprocessor search for include files in
/usr/5include
before searching for them in
/usr/include.
OPTIONS
In addition to the
-D,
-I
and
-U
options (which are identical to their interpretation by
cc.1v
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 filename
-
Direct output to named
file.
- -s
-
Operate silently; does not print input file names.
- -t
-
Format listing for 80-column width.
FILES
- /usr/tmp/xr*
-
temporary files
SEE ALSO
cc.1v
cpp.1
DIAGNOSTICS
Error messages are unusually cryptic, but usually mean
that you cannot compile these files, anyway.
NOTES
While the compiler allows 8-bit strings and comments,
8-bits are not allowed anywhere else.
See
cc.1v
for an explanation about why
cc
is not 8-bit clean.
BUGS
cxref
considers a formal argument in a
#define
macro definition to be a declaration of that symbol. For example,
a program that
#includes
ctype.h,
will contain many declarations of the variable
c.
