| 55 | =head1 DESCRIPTION
|
|---|
| 56 |
|
|---|
| 57 | The following is the old c2ph.doc documentation by Tom Christiansen
|
|---|
| 58 | <[email protected]>
|
|---|
| 59 | Date: 25 Jul 91 08:10:21 GMT
|
|---|
| 60 |
|
|---|
| 61 | Once upon a time, I wrote a program called pstruct. It was a perl
|
|---|
| 62 | program that tried to parse out C structures and display their member
|
|---|
| 63 | offsets for you. This was especially useful for people looking at
|
|---|
| 64 | binary dumps or poking around the kernel.
|
|---|
| 65 |
|
|---|
| 66 | Pstruct was not a pretty program. Neither was it particularly robust.
|
|---|
| 67 | The problem, you see, was that the C compiler was much better at parsing
|
|---|
| 68 | C than I could ever hope to be.
|
|---|
| 69 |
|
|---|
| 70 | So I got smart: I decided to be lazy and let the C compiler parse the C,
|
|---|
| 71 | which would spit out debugger stabs for me to read. These were much
|
|---|
| 72 | easier to parse. It's still not a pretty program, but at least it's more
|
|---|
| 73 | robust.
|
|---|
| 74 |
|
|---|
| 75 | Pstruct takes any .c or .h files, or preferably .s ones, since that's
|
|---|
| 76 | the format it is going to massage them into anyway, and spits out
|
|---|
| 77 | listings like this:
|
|---|
| 78 |
|
|---|
| 79 | struct tty {
|
|---|
| 80 | int tty.t_locker 000 4
|
|---|
| 81 | int tty.t_mutex_index 004 4
|
|---|
| 82 | struct tty * tty.t_tp_virt 008 4
|
|---|
| 83 | struct clist tty.t_rawq 00c 20
|
|---|
| 84 | int tty.t_rawq.c_cc 00c 4
|
|---|
| 85 | int tty.t_rawq.c_cmax 010 4
|
|---|
| 86 | int tty.t_rawq.c_cfx 014 4
|
|---|
| 87 | int tty.t_rawq.c_clx 018 4
|
|---|
| 88 | struct tty * tty.t_rawq.c_tp_cpu 01c 4
|
|---|
| 89 | struct tty * tty.t_rawq.c_tp_iop 020 4
|
|---|
| 90 | unsigned char * tty.t_rawq.c_buf_cpu 024 4
|
|---|
| 91 | unsigned char * tty.t_rawq.c_buf_iop 028 4
|
|---|
| 92 | struct clist tty.t_canq 02c 20
|
|---|
| 93 | int tty.t_canq.c_cc 02c 4
|
|---|
| 94 | int tty.t_canq.c_cmax 030 4
|
|---|
| 95 | int tty.t_canq.c_cfx 034 4
|
|---|
| 96 | int tty.t_canq.c_clx 038 4
|
|---|
| 97 | struct tty * tty.t_canq.c_tp_cpu 03c 4
|
|---|
| 98 | struct tty * tty.t_canq.c_tp_iop 040 4
|
|---|
| 99 | unsigned char * tty.t_canq.c_buf_cpu 044 4
|
|---|
| 100 | unsigned char * tty.t_canq.c_buf_iop 048 4
|
|---|
| 101 | struct clist tty.t_outq 04c 20
|
|---|
| 102 | int tty.t_outq.c_cc 04c 4
|
|---|
| 103 | int tty.t_outq.c_cmax 050 4
|
|---|
| 104 | int tty.t_outq.c_cfx 054 4
|
|---|
| 105 | int tty.t_outq.c_clx 058 4
|
|---|
| 106 | struct tty * tty.t_outq.c_tp_cpu 05c 4
|
|---|
| 107 | struct tty * tty.t_outq.c_tp_iop 060 4
|
|---|
| 108 | unsigned char * tty.t_outq.c_buf_cpu 064 4
|
|---|
| 109 | unsigned char * tty.t_outq.c_buf_iop 068 4
|
|---|
| 110 | (*int)() tty.t_oproc_cpu 06c 4
|
|---|
| 111 | (*int)() tty.t_oproc_iop 070 4
|
|---|
| 112 | (*int)() tty.t_stopproc_cpu 074 4
|
|---|
| 113 | (*int)() tty.t_stopproc_iop 078 4
|
|---|
| 114 | struct thread * tty.t_rsel 07c 4
|
|---|
| 115 |
|
|---|
| 116 | etc.
|
|---|
| 117 |
|
|---|
| 118 |
|
|---|
| 119 | Actually, this was generated by a particular set of options. You can control
|
|---|
| 120 | the formatting of each column, whether you prefer wide or fat, hex or decimal,
|
|---|
| 121 | leading zeroes or whatever.
|
|---|
| 122 |
|
|---|
| 123 | All you need to be able to use this is a C compiler than generates
|
|---|
| 124 | BSD/GCC-style stabs. The B<-g> option on native BSD compilers and GCC
|
|---|
| 125 | should get this for you.
|
|---|
| 126 |
|
|---|
| 127 | To learn more, just type a bogus option, like B<-\?>, and a long usage message
|
|---|
| 128 | will be provided. There are a fair number of possibilities.
|
|---|
| 129 |
|
|---|
| 130 | If you're only a C programmer, than this is the end of the message for you.
|
|---|
| 131 | You can quit right now, and if you care to, save off the source and run it
|
|---|
| 132 | when you feel like it. Or not.
|
|---|
| 133 |
|
|---|
| 134 |
|
|---|
| 135 |
|
|---|
| 136 | But if you're a perl programmer, then for you I have something much more
|
|---|
| 137 | wondrous than just a structure offset printer.
|
|---|
| 138 |
|
|---|
| 139 | You see, if you call pstruct by its other incybernation, c2ph, you have a code
|
|---|
| 140 | generator that translates C code into perl code! Well, structure and union
|
|---|
| 141 | declarations at least, but that's quite a bit.
|
|---|
| 142 |
|
|---|
| 143 | Prior to this point, anyone programming in perl who wanted to interact
|
|---|
| 144 | with C programs, like the kernel, was forced to guess the layouts of
|
|---|
| 145 | the C structures, and then hardwire these into his program. Of course,
|
|---|
| 146 | when you took your wonderfully crafted program to a system where the
|
|---|
| 147 | sgtty structure was laid out differently, your program broke. Which is
|
|---|
| 148 | a shame.
|
|---|
| 149 |
|
|---|
| 150 | We've had Larry's h2ph translator, which helped, but that only works on
|
|---|
| 151 | cpp symbols, not real C, which was also very much needed. What I offer
|
|---|
| 152 | you is a symbolic way of getting at all the C structures. I've couched
|
|---|
| 153 | them in terms of packages and functions. Consider the following program:
|
|---|
| 154 |
|
|---|
| 155 | #!/usr/local/bin/perl
|
|---|
| 156 |
|
|---|
| 157 | require 'syscall.ph';
|
|---|
| 158 | require 'sys/time.ph';
|
|---|
| 159 | require 'sys/resource.ph';
|
|---|
| 160 |
|
|---|
| 161 | $ru = "\0" x &rusage'sizeof();
|
|---|
| 162 |
|
|---|
| 163 | syscall(&SYS_getrusage, &RUSAGE_SELF, $ru) && die "getrusage: $!";
|
|---|
| 164 |
|
|---|
| 165 | @ru = unpack($t = &rusage'typedef(), $ru);
|
|---|
| 166 |
|
|---|
| 167 | $utime = $ru[ &rusage'ru_utime + &timeval'tv_sec ]
|
|---|
| 168 | + ($ru[ &rusage'ru_utime + &timeval'tv_usec ]) / 1e6;
|
|---|
| 169 |
|
|---|
| 170 | $stime = $ru[ &rusage'ru_stime + &timeval'tv_sec ]
|
|---|
| 171 | + ($ru[ &rusage'ru_stime + &timeval'tv_usec ]) / 1e6;
|
|---|
| 172 |
|
|---|
| 173 | printf "you have used %8.3fs+%8.3fu seconds.\n", $utime, $stime;
|
|---|
| 174 |
|
|---|
| 175 |
|
|---|
| 176 | As you see, the name of the package is the name of the structure. Regular
|
|---|
| 177 | fields are just their own names. Plus the following accessor functions are
|
|---|
| 178 | provided for your convenience:
|
|---|
| 179 |
|
|---|
| 180 | struct This takes no arguments, and is merely the number of first-level
|
|---|
| 181 | elements in the structure. You would use this for indexing
|
|---|
| 182 | into arrays of structures, perhaps like this
|
|---|
| 183 |
|
|---|
| 184 |
|
|---|
| 185 | $usec = $u[ &user'u_utimer
|
|---|
| 186 | + (&ITIMER_VIRTUAL * &itimerval'struct)
|
|---|
| 187 | + &itimerval'it_value
|
|---|
| 188 | + &timeval'tv_usec
|
|---|
| 189 | ];
|
|---|
| 190 |
|
|---|
| 191 | sizeof Returns the bytes in the structure, or the member if
|
|---|
| 192 | you pass it an argument, such as
|
|---|
| 193 |
|
|---|
| 194 | &rusage'sizeof(&rusage'ru_utime)
|
|---|
| 195 |
|
|---|
| 196 | typedef This is the perl format definition for passing to pack and
|
|---|
| 197 | unpack. If you ask for the typedef of a nothing, you get
|
|---|
| 198 | the whole structure, otherwise you get that of the member
|
|---|
| 199 | you ask for. Padding is taken care of, as is the magic to
|
|---|
| 200 | guarantee that a union is unpacked into all its aliases.
|
|---|
| 201 | Bitfields are not quite yet supported however.
|
|---|
| 202 |
|
|---|
| 203 | offsetof This function is the byte offset into the array of that
|
|---|
| 204 | member. You may wish to use this for indexing directly
|
|---|
| 205 | into the packed structure with vec() if you're too lazy
|
|---|
| 206 | to unpack it.
|
|---|
| 207 |
|
|---|
| 208 | typeof Not to be confused with the typedef accessor function, this
|
|---|
| 209 | one returns the C type of that field. This would allow
|
|---|
| 210 | you to print out a nice structured pretty print of some
|
|---|
| 211 | structure without knoning anything about it beforehand.
|
|---|
| 212 | No args to this one is a noop. Someday I'll post such
|
|---|
| 213 | a thing to dump out your u structure for you.
|
|---|
| 214 |
|
|---|
| 215 |
|
|---|
| 216 | The way I see this being used is like basically this:
|
|---|
| 217 |
|
|---|
| 218 | % h2ph <some_include_file.h > /usr/lib/perl/tmp.ph
|
|---|
| 219 | % c2ph some_include_file.h >> /usr/lib/perl/tmp.ph
|
|---|
| 220 | % install
|
|---|
| 221 |
|
|---|
| 222 | It's a little tricker with c2ph because you have to get the includes right.
|
|---|
| 223 | I can't know this for your system, but it's not usually too terribly difficult.
|
|---|
| 224 |
|
|---|
| 225 | The code isn't pretty as I mentioned -- I never thought it would be a 1000-
|
|---|
| 226 | line program when I started, or I might not have begun. :-) But I would have
|
|---|
| 227 | been less cavalier in how the parts of the program communicated with each
|
|---|
| 228 | other, etc. It might also have helped if I didn't have to divine the makeup
|
|---|
| 229 | of the stabs on the fly, and then account for micro differences between my
|
|---|
| 230 | compiler and gcc.
|
|---|
| 231 |
|
|---|
| 232 | Anyway, here it is. Should run on perl v4 or greater. Maybe less.
