CXREF(CP) XENIX System V CXREF(CP)
Name
cxref - Generates C program cross-reference.
Syntax
cxref [ options ] file ...
Description
cxref analyzes a collection of C files and attempts to build
a cross-reference table. cxref uses a special version of
cpp to include information defined by #define in its symbol
table. It produces a listing on the standard output of all
symbols (auto, static, and global) for each separate file,
or with the -c option for the combined files. Each symbol
contains an asterisk (*) before the declaring reference.
In addition to the -D, -I and -U options (which are
identical to their interpretation by cc(CP)), the following
options are interpreted by cxref:
-c Prints a combined cross-reference of all input
files.
-w<num> Formats output no wider than <num> (decimal)
columns. The default is 80 if <num> is not
specified or is less than 51.
-o file Directs output to named file.
-s Operates silently; does not print input
filenames.
-t Formats listing for 80-column width.
Files
/usr/lib/xcpp special version of C-preprocessor.

Diagnostics
Error messages are cryptic, but usually mean that you cannot
compile these files.
Notes
cxref considers a formal argument in a #define macro
definition to be a declaration of that symbol. For example,
a program that contains ``#include ctype.h '' will have many
declarations of the variable c.
