NAME

cxref − generate C program cross reference

SYNOPSIS

cxref [ options ] files

DESCRIPTION

Cxref analyzes a collection of C files and attempts to build a cross reference table.  Cxref utilizes 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 identical to their interpretation by cc(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 named file. 

−s Operate silently; does not print input file names. 

−t Format listing for 80-column width. 

FILES

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

SEE ALSO

cc(1). 

DIAGNOSTICS

Error messages are unusually cryptic, but usually mean that you can’t compile these files, anyway.
