RE		 2#
3# generate a .def file
4#
5# It does this by parsing the header files and looking for the
47339f61 6# prototyped functions: it then prunes the output.
d02b48c6 7#
948d0125
RL		 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
62dc5aad 40# symbol name variants for platforms where the names are too long for the
948d0125 41# compiler or linker, or if the systems is case insensitive and there is a
62dc5aad
RL		 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
5012158a
LJ		 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
62dc5aad
RL		 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.
948d0125
RL		 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.
