CXREF(1) (Advanced C Utilities) CXREF(1)
NAME
cxref - generate C program cross-reference
SYNOPSIS
cxref [ options ] files
DESCRIPTION
The cxref command analyzes a collection of C files and
attempts to build a cross-reference table. cxref uses 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
interpreted just as they are by cc(1) and cpp(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 file.
-s Operate silently; do not print input file names.
-t Format listing for 80-column width.
FILES
LLIBDIR usually /usr/lib
LLIBDIR/xcpp special version of the C preprocessor.

DIAGNOSTICS
Error messages are unusually cryptic, but usually mean that
you cannot compile these files.
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.
