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 ...
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.
|-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
|-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.|
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
|/usr/ccs/lib/xpass||Special version of C compiler first-pass.|
|/usr/ccs/bin/cxref||Contains the cxref command.|
