| 97 | =head1 DESCRIPTION
|
|---|
| 98 |
|
|---|
| 99 | The following is the old c2ph.doc documentation by Tom Christiansen
|
|---|
| 100 | <[email protected]>
|
|---|
| 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:
|
|---|
| 120 |
|
|---|
| 121 | struct tty {
|
|---|
| 122 | int tty.t_locker 000 4
|
|---|
| 123 | int tty.t_mutex_index 004 4
|
|---|
| 124 | struct tty * tty.t_tp_virt 008 4
|
|---|
| 125 | struct clist tty.t_rawq 00c 20
|
|---|
| 126 | int tty.t_rawq.c_cc 00c 4
|
|---|
| 127 | int tty.t_rawq.c_cmax 010 4
|
|---|
| 128 | int tty.t_rawq.c_cfx 014 4
|
|---|
| 129 | int tty.t_rawq.c_clx 018 4
|
|---|
| 130 | struct tty * tty.t_rawq.c_tp_cpu 01c 4
|
|---|
| 131 | struct tty * tty.t_rawq.c_tp_iop 020 4
|
|---|
| 132 | unsigned char * tty.t_rawq.c_buf_cpu 024 4
|
|---|
| 133 | unsigned char * tty.t_rawq.c_buf_iop 028 4
|
|---|
| 134 | struct clist tty.t_canq 02c 20
|
|---|
| 135 | int tty.t_canq.c_cc 02c 4
|
|---|
| 136 | int tty.t_canq.c_cmax 030 4
|
|---|
| 137 | int tty.t_canq.c_cfx 034 4
|
|---|
| 138 | int tty.t_canq.c_clx 038 4
|
|---|
| 139 | struct tty * tty.t_canq.c_tp_cpu 03c 4
|
|---|
| 140 | struct tty * tty.t_canq.c_tp_iop 040 4
|
|---|
| 141 | unsigned char * tty.t_canq.c_buf_cpu 044 4
|
|---|
| 142 | unsigned char * tty.t_canq.c_buf_iop 048 4
|
|---|
| 143 | struct clist tty.t_outq 04c 20
|
|---|
| 144 | int tty.t_outq.c_cc 04c 4
|
|---|
| 145 | int tty.t_outq.c_cmax 050 4
|
|---|
| 146 | int tty.t_outq.c_cfx 054 4
|
|---|
| 147 | int tty.t_outq.c_clx 058 4
|
|---|
| 148 | struct tty * tty.t_outq.c_tp_cpu 05c 4
|
|---|
| 149 | struct tty * tty.t_outq.c_tp_iop 060 4
|
|---|
| 150 | unsigned char * tty.t_outq.c_buf_cpu 064 4
|
|---|
| 151 | unsigned char * tty.t_outq.c_buf_iop 068 4
|
|---|
| 152 | (*int)() tty.t_oproc_cpu 06c 4
|
|---|
| 153 | (*int)() tty.t_oproc_iop 070 4
|
|---|
| 154 | (*int)() tty.t_stopproc_cpu 074 4
|
|---|
| 155 | (*int)() tty.t_stopproc_iop 078 4
|
|---|
| 156 | struct thread * tty.t_rsel 07c 4
|
|---|
| 157 |
|
|---|
| 158 | etc.
|
|---|
| 159 |
|
|---|
| 160 |
|
|---|
| 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
|
|---|
| 166 | BSD/GCC-style stabs. The B<-g> option on native BSD compilers and GCC
|
|---|
| 167 | should get this for you.
|
|---|
| 168 |
|
|---|
| 169 | To learn more, just type a bogus option, like B<-\?>, and a long usage message
|
|---|
| 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
|
|---|
| 187 | the C structures, and then hardwire these into his program. Of course,
|
|---|
| 188 | when you took your wonderfully crafted program to a system where the
|
|---|
| 189 | sgtty structure was laid out differently, your program broke. Which is
|
|---|
| 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
|
|---|
| 219 | fields are just their own names. Plus the following accessor functions are
|
|---|
| 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.
