cxref(1)
NAME
cxref − generate C program cross reference
SYNTAX
cxref [options] files
DESCRIPTION
The cxref command analyzes a collection of C files and attempts to build a cross reference table. The cxref command 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.
OPTIONS
−c Prints a combined cross-reference of all input files.
−Dname Defines name to processor, as if by #define. Default value is 1.
−Idir Searches named directory for #include files whose names do not begin with a backslash (/).
−lx Abbreviation for library name /lib/libx.a, where x is a string. The libraries /usr/lib/libx.a and /usr/local/lib/libx.a are searched in sequence.
−ofile Directs output to named file.
−s Operates silently; does not print input file names.
−t Formats listing for 80-column width.
−Uname Removes any initial definition of name.
−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.
DIAGNOSTICS
Error messages are difficult to understand. They usually mean that you cannot compile the files.
