   2 #
   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 replacements 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.  This script assumes those redefinitions are place in the file
  43 #   crypto/idhacks.h.
  44 # - "kind" is "FUNCTION" or "VARIABLE".  The meaning of that is obvious.
  45 # - "algorithms" is a comma-separated list of algorithm names.  This helps
  46 #   exclude symbols that are part of an algorithm that some user wants to
  47 #   exclude.
