97 | =head1 DESCRIPTION | |
98 | ||
99 | The following is the old c2ph.doc documentation by Tom Christiansen | |
100 | <tchrist@perl.com> | |
101 | Date: 25 Jul 91 08:10:21 GMT | |
102 | ||
103 | Once upon a time, I wrote a program called pstruct. It was a perl | |
104 | program that tried to parse out C structures and display their member | |
105 | offsets for you. This was especially useful for people looking at | |
106 | binary dumps or poking around the kernel. | |
107 | ||
108 | Pstruct was not a pretty program. Neither was it particularly robust. | |
109 | The problem, you see, was that the C compiler was much better at parsing | |
110 | C than I could ever hope to be. | |
111 | ||
112 | So I got smart: I decided to be lazy and let the C compiler parse the C, | |
113 | which would spit out debugger stabs for me to read. These were much | |
114 | easier to parse. It's still not a pretty program, but at least it's more | |
115 | robust. | |
116 | ||
117 | Pstruct takes any .c or .h files, or preferably .s ones, since that's | |
118 | the format it is going to massage them into anyway, and spits out | |
119 | listings like this: | |

161 | Actually, this was generated by a particular set of options. You can control | |
162 | the formatting of each column, whether you prefer wide or fat, hex or decimal, | |
163 | leading zeroes or whatever. | |
164 | ||
165 | All you need to be able to use this is a C compiler than generates | |
1fef88e7 | 166 | BSD/GCC-style stabs. The B<-g> option on native BSD compilers and GCC |
9aec1e06 | 167 | should get this for you. |
168 | ||
1fef88e7 | 169 | To learn more, just type a bogus option, like B<-\?>, and a long usage message |
9aec1e06 | 170 | will be provided. There are a fair number of possibilities. |
171 | ||
172 | If you're only a C programmer, than this is the end of the message for you. | |
173 | You can quit right now, and if you care to, save off the source and run it | |
174 | when you feel like it. Or not. | |
175 | ||
176 | ||
177 | ||
178 | But if you're a perl programmer, then for you I have something much more | |
179 | wondrous than just a structure offset printer. | |
180 | ||
181 | You see, if you call pstruct by its other incybernation, c2ph, you have a code | |
182 | generator that translates C code into perl code! Well, structure and union | |
183 | declarations at least, but that's quite a bit. | |
184 | ||
185 | Prior to this point, anyone programming in perl who wanted to interact | |
186 | with C programs, like the kernel, was forced to guess the layouts of | |
5d0b5eb0 | 187 | the C structures, and then hardwire these into his program. Of course, |
9aec1e06 | 188 | when you took your wonderfully crafted program to a system where the |
5d0b5eb0 | 189 | sgtty structure was laid out differently, your program broke. Which is |
9aec1e06 | 190 | a shame. |
191 | ||
192 | We've had Larry's h2ph translator, which helped, but that only works on | |
193 | cpp symbols, not real C, which was also very much needed. What I offer | |
194 | you is a symbolic way of getting at all the C structures. I've couched | |
195 | them in terms of packages and functions. Consider the following program: | |
196 | ||
197 | #!/usr/local/bin/perl | |
198 | ||
199 | require 'syscall.ph'; | |
200 | require 'sys/time.ph'; | |
201 | require 'sys/resource.ph'; | |
202 | ||
203 | $ru = "\0" x &rusage'sizeof(); | |
204 | ||
205 | syscall(&SYS_getrusage, &RUSAGE_SELF, $ru) && die "getrusage: $!"; | |
206 | ||
207 | @ru = unpack($t = &rusage'typedef(), $ru); | |
208 | ||
209 | $utime = $ru[ &rusage'ru_utime + &timeval'tv_sec ] | |
210 | + ($ru[ &rusage'ru_utime + &timeval'tv_usec ]) / 1e6; | |
211 | ||
212 | $stime = $ru[ &rusage'ru_stime + &timeval'tv_sec ] | |
213 | + ($ru[ &rusage'ru_stime + &timeval'tv_usec ]) / 1e6; | |
214 | ||
215 | printf "you have used %8.3fs+%8.3fu seconds.\n", $utime, $stime; | |
216 | ||
217 | ||
218 | As you see, the name of the package is the name of the structure. Regular | |
1fef88e7 | 219 | fields are just their own names. Plus the following accessor functions are |
9aec1e06 | 220 | provided for your convenience: |
221 | ||
222 | struct This takes no arguments, and is merely the number of first-level | |
223 | elements in the structure. You would use this for indexing | |
224 | into arrays of structures, perhaps like this | |
225 | ||
226 | ||
227 | $usec = $u[ &user'u_utimer | |
228 | + (&ITIMER_VIRTUAL * &itimerval'struct) | |
229 | + &itimerval'it_value | |
230 | + &timeval'tv_usec | |
231 | ]; | |
232 | ||
233 | sizeof Returns the bytes in the structure, or the member if | |
234 | you pass it an argument, such as | |
235 | ||
236 | &rusage'sizeof(&rusage'ru_utime) | |
237 | ||
238 | typedef This is the perl format definition for passing to pack and | |
239 | unpack. If you ask for the typedef of a nothing, you get | |
240 | the whole structure, otherwise you get that of the member | |
241 | you ask for. Padding is taken care of, as is the magic to | |
242 | guarantee that a union is unpacked into all its aliases. | |
243 | Bitfields are not quite yet supported however. | |
244 | ||
245 | offsetof This function is the byte offset into the array of that | |
246 | member. You may wish to use this for indexing directly | |
247 | into the packed structure with vec() if you're too lazy | |
248 | to unpack it. | |
249 | ||
250 | typeof Not to be confused with the typedef accessor function, this | |
251 | one returns the C type of that field. This would allow | |
252 | you to print out a nice structured pretty print of some | |
253 | structure without knoning anything about it beforehand. | |
254 | No args to this one is a noop. Someday I'll post such | |
255 | a thing to dump out your u structure for you. | |
256 | ||
257 | ||
258 | The way I see this being used is like basically this: | |
259 | ||
260 | % h2ph <some_include_file.h > /usr/lib/perl/tmp.ph | |
261 | % c2ph some_include_file.h >> /usr/lib/perl/tmp.ph | |
262 | % install | |
263 | ||
264 | It's a little tricker with c2ph because you have to get the includes right. | |
265 | I can't know this for your system, but it's not usually too terribly difficult. | |
266 | ||
267 | The code isn't pretty as I mentioned -- I never thought it would be a 1000- | |
268 | line program when I started, or I might not have begun. :-) But I would have | |
269 | been less cavalier in how the parts of the program communicated with each | |
270 | other, etc. It might also have helped if I didn't have to divine the makeup | |
271 | of the stabs on the fly, and then account for micro differences between my | |
272 | compiler and gcc. | |
273 | ||
274 | Anyway, here it is. Should run on perl v4 or greater. Maybe less. | |
