Readme: | Short: Generate a program flowgraph Author: gray@gnu.org (Sergey Poznyakoff), port by uploader Uploader: polluks+aminet sdf lonestar org (Stefan Haubenthal) Type: dev/c Version: 1.6 Architecture: ppc-morphos URL: https://www.gnu.org/software/cflow/
Usage: cflow [OPTION...] [FILE]... generate a program flowgraph
General options: -d, --depth=NUMBER Set the depth at which the flowgraph is cut off -f, --format=NAME Use given output format NAME. Valid names are `gnu' (default) and `posix' -i, --include=CLASSES Include specified classes of symbols (see below). Prepend CLASSES with ^ or - to exclude them from the output -o, --output=FILE Set output file name (default -, meaning stdout) -r, --reverse * Print reverse call tree -x, --xref Produce cross-reference listing only
Symbols classes for --include argument
_ symbols whose names begin with an underscore s static symbols t typedefs (for cross-references only) x all data symbols, both external and static
Parser control:
-D, --define=NAME[=DEFN] Predefine NAME as a macro -I, --include-dir=DIR Add the directory DIR to the list of directories to be searched for header files. -S, --use-indentation * Rely on indentation -U, --undefine=NAME Cancel any previous definition of NAME -a, --ansi * Accept only sources in ANSI C -m, --main=NAME Assume main function to be called NAME --no-main There's no main function; print graphs for all functions in the program -p, --pushdown=NUMBER Set initial token stack size to NUMBER --preprocess[=COMMAND], --cpp[=COMMAND] * Run the specified preprocessor command -s, --symbol=SYMBOL:[=]TYPE Register SYMBOL with given TYPE, or define an alias (if := is used). Valid types are: keyword (or kw), modifier, qualifier, identifier, type, wrapper. Any unambiguous abbreviation of the above is also accepted
Output control:
-A, --all Show all functions, not only those reachable from main -T, --tree * Draw ASCII art tree -b, --brief * Brief output --emacs * Additionally format output for use with GNU Emacs --level-indent=ELEMENT Control graph appearance -l, --print-level * Print nesting level along with the call tree -n, --number * Print line numbers --omit-arguments * Do not print argument lists in function declarations --omit-symbol-names * Do not print symbol names in declaration strings
Informational options:
--debug[=NUMBER] Set debugging level -v, --verbose * Verbose error diagnostics
-?, --help give this help list -V, --version print program version --usage give a short usage message
Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
* The effect of each option marked with an asterisk is reversed if the option's long name is prefixed with `no-'. For example, --no-cpp cancels --cpp.
