AIX Version 4.3 Commands Reference, Volume 1
cxref Command
Purpose
Creates a C and C++ program cross-reference listing.
cxref [ -c ] [ -o File ] [ -qOption ] [ -s ] [ -t ] [ -w Number ]
[ [ -D Name [ =Definition ] ] [ -I Directory ] [ -U Name ] ] ... [ -NdNumber ]
[ -NlNumber ] [ -NnNumber ] [ -NtNumber ] File ...
Description
The cxref command analyzes C and C++ program Files and creates a cross-reference table, using the cpp command to include #define directives in its symbol table. It writes to standard output a listing of all symbols in each file processed, either separately or in combination (see the -c flag). The formal parameters in a function definition are always listed; but if a function is only prototyped and not defined, the parameters are not listed. When a reference to a symbol is that symbol's declaration, an * (asterisk) precedes it.
Flags
| -c |
Displays a combined listing of the cross-references in all input files. |
| -o File |
Directs the output to the specified File. |
| -s |
Does not display the input file names. |
| -t |
Makes the listing 80 columns wide. |
| -w Number |
Makes the listing Number columns wide, where Number is a decimal integer greater than or equal to 51. If Number is less than 51, the listing will be 80 columns wide. |
| -NdNumber |
Changes the dimension table size to Number. The default is 2000. |
| -NlNumber |
Changes the number of type nodes to Number. The default is 8000. |
| -NnNumber |
Changes the symbol table size to Number. The default is 1500. |
| -NtNumber |
Changes the number of tree nodes to Number. The default is 1000. |
In addition, the cxref command recognizes the following flags of the cpp command (macro preprocessor):
| -D Name[=Definition] |
Defines Name as in a #define directive. The default definition is 1. |
| -I Directory |
Looks first in directory, then looks in the directories on the standard list for #include files with names that do not begin with a slash (/) (see the cpp command). |
| -U Name |
Removes any initial definition of Name, where Name is a reserved symbol predefined by the preprocessor. |
| -qOption |
Pass -qOption to the preprocessor. For example, -qmbcs sets multibyte mode specified by the current locale, and -qidirfirst modifies the search order for files included with the #include file_name directive. |
Examples
To provide a combined cross-reference listing of stdin1.c and stdin2.c, making the output 80 columns wide, enter:
cxref -c -t stdin1.c stdin2.c > output
Files
| /usr/ccs/lib/xpass |
Special version of C compiler first-pass. |
| /usr/ccs/bin/cxref |
Contains the cxref command. |
