3 # generate a .def file
4 #
5 # It does this by parsing the header files and looking for the
6 # prototyped functions: it then prunes the output.
7 #
8 # Intermediary files are created, call libeay.num and ssleay.num,...
9 # Previously, they had the following format:
10 #
11 # routine-name nnnn
12 #
13 # But that isn't enough for a number of reasons, the first on being that
14 # this format is (needlessly) very Win32-centric, and even then...
15 # One of the biggest problems is that there's no information about what
16 # routines should actually be used, which varies with what crypto algorithms
17 # are disabled. Also, some operating systems (for example VMS with VAX C)
18 # need to keep track of the global variables as well as the functions.
19 #
20 # So, a remake of this script is done so as to include information on the
21 # kind of symbol it is (function or variable) and what algorithms they're
22 # part of. This will allow easy translating to .def files or the corresponding
23 # file in other operating systems (a .opt file for VMS, possibly with a .mar
24 # file).
25 #
26 # The format now becomes:
27 #
28 # routine-name nnnn info
29 #
30 # and the "info" part is actually a colon-separated string of fields with
31 # the following meaning:
32 #
33 # existence:platform:kind:algorithms
34 #
35 # - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
36 # found somewhere in the source,
37 # - "platforms" is empty if it exists on all platforms, otherwise it contains
38 # comma-separated list of the platform, just as they are if the symbol exists
39 # for those platforms, or prepended with a "!" if not. This helps resolve
40 # symbol name variants for platforms where the names are too long for the
41 # compiler or linker, or if the systems is case insensitive and there is a
42 # clash, or the symbol is implemented differently (see
43 # EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
44 # in the file crypto/symhacks.h.
45 # The semantics for the platforms is that every item is checked against the
46 # environment. For the negative items ("!FOO"), if any of them is false
47 # (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
48 # used. For the positive itms, if all of them are false in the environment,
49 # the corresponding symbol can't be used. Any combination of positive and
50 # negative items are possible, and of course leave room for some redundancy.
51 # - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
52 # - "algorithms" is a comma-separated list of algorithm names. This helps
53 # exclude symbols that are part of an algorithm that some user wants to
54 # exclude.
