proto - make prototyped C source compatible with K&R, ANSI and C++

proto converts ANSI C prototype constructs in file to constructs compatible with K&R C, ANSI C, and C++. Only files with the line #pragma prototyped appearing in one of the first 64 lines are processed; other files are silently ignored. Output is written to the standard output unless the --replace option is specified, in which case file is modified in-place.

-c, --comment=bme

b[m[e]] are the beginning, middle, and end comment characters. If e is omitted then it defaults to b. If m is omitted then it defaults to b. Use "/*" for C comments, "#" for shell, and "(*)" for pascal. If bme is "" (the empty string) then the comment style is determined from the input file suffix; no notice is prepended if the comment style cannot be determined. The default value is "/*".

-d, --disable

Disable prototype conversion but still emit the identification comment.

-e, --externs=package

All extern references are for package. Some systems require special attributes for imported and exported dll data symbols. If _BLD_package is not defined then extern data references will be assigned the dll import attribute when supported by the local compiler.

-f, --force

Force conversion for files that do not contain #pragma prototyped.

-h, --header

Emit the proto header definition preamble. On by default; -h means --noheader.

-i, --inverse

Specifies inverse proto: classic function definitions are converted to ANSI prototype form and non-ANSI directives are commented out. In this case files with the line #pragma noprototyped within the first 64 lines are silently ignored. If --header is also specified then only extern prototypes are emitted for each non-static function. This option requires that all classic function formal arguments be declared, i.e., omitted declarations for int formals will not generate the correct prototype. Typical usage would be to first run proto --inverse --header *.c to generate the external prototypes that should be placed in a .h file shared by *.c and then proto --inverse --replace *.c to convert the function prototypes in place. Note that prototype code conditioned on __STDC__ will most likely confuse --inverse .

-l, --license=file

Generate a license notice comment at the top of the output controlled by one or more name=value pairs in file. If a value contains space characters then it must be enclosed in either single or double quotes. name may be:

type

The license type:

bsd

The BSD open source license.

cpl

The Common Public License.

epl

The Eclipse Public License.

gpl

The GNU Public License.

mit

The MIT open source license.

inline

License text already in source.

none

No license.

noncommercial

Non-commercial use.

nonexclusive

Single person non-commercial use.

open

Open source.

proprietary

Only by individual agreement.

special

License text in notice.

usage

License specific optget(3) usage strings.

verbose

Include the disclaimer notice if any.

zlib

The ZLIB open source license.

author

A , separated list of name <email> pairs.

class

The license class. The default values are:

gpl

The GNU Public License.

open

www.opensource.org sanctioned open source.

proprietary

Internal or non-disclosure use only.

special

Nonstandard license text and notices.

corporation

Within the parent, e.g., AT&T.

company

Within the corporation, e.g., Research.

location

Company location.

organization

Within the company, e.g., Network Services Research Department.

notice

type=special notice text with embedded newlines or additional notice text listed by type=verbose.

package

The generic software package name, e.g., ast.

parent

They own it all, e.g., AT&T.

since

The year the software was first released.

source

The year the input files was modified.

start

The year the license was first applied to the software.

url

The URL of the detailed license text, e.g., http://www.research.att.com/sw/license/open-ast.html .

urlmd5

The md5sum(1) of the downloaded URL data. Note that the downloaded data may have embedded \r not present in the original source.

query=text

If text is one of the names above then its value is expanded, otherwise ${name} in text is expanded. The result is printed as a line on the standard output and proto exits. This should only be used via --options.

-n, --sync

Output C style line syncs to retain the original line structure.

-o, --options=name=value,...

Additional space or , separated name=value --license options.

-p, --pass

Pass input to output, even if not converted.

-r, --replace

Process the input files in place; original information is replaced by proto output.

-s, --include

Output #include <prototyped.h> rather than expanding the equivalent inline.

-t, --test

Enable test code. Use at your own risk.

-v, --verbose

List each file as it is processed.

-x, --externalize

Convert static function attributes to extern. Used for analysis programs that only instrument extern functions.

-z, --zap

Disable conversion and remove #pragma prototyped.

-C, --copy=directory

Convert each input file to directory/file, making intermediate directories as necessary.

-L, --list=file

Input file names are read one per line from file.

-P|+, --plusplus

Convert extern() to extern(...).

-S, --shell

Equivalent to --comment="#".
