5 # It does this by parsing the header files and looking for the
6 # prototyped functions: it then prunes the output.
8 # Intermediary files are created, call libcrypto.num and libssl.num,
9 # The format of these files is:
11 # routine-name nnnn vers info
13 # The "nnnn" and "vers" fields are the numeric id and version for the symbol
14 # respectively. The "info" part is actually a colon-separated string of fields
15 # with the following meaning:
17 # existence:platform:kind:algorithms
19 # - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
20 # found somewhere in the source,
21 # - "platforms" is empty if it exists on all platforms, otherwise it contains
22 # comma-separated list of the platform, just as they are if the symbol exists
23 # for those platforms, or prepended with a "!" if not. This helps resolve
24 # symbol name variants for platforms where the names are too long for the
25 # compiler or linker, or if the systems is case insensitive and there is a
26 # clash, or the symbol is implemented differently (see
27 # EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
28 # in the file crypto/symhacks.h.
29 # The semantics for the platforms is that every item is checked against the
30 # environment. For the negative items ("!FOO"), if any of them is false
31 # (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
32 # used. For the positive itms, if all of them are false in the environment,
33 # the corresponding symbol can't be used. Any combination of positive and
34 # negative items are possible, and of course leave room for some redundancy.
35 # - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
36 # - "algorithms" is a comma-separated list of algorithm names. This helps
37 # exclude symbols that are part of an algorithm that some user wants to
43 use File::Spec::Functions;
