OPENSSL_USER_MACROS(7SSL)                    OpenSSL                    OPENSSL_USER_MACROS(7SSL)

NAME
       openssl_user_macros, OPENSSL_API_COMPAT, OPENSSL_NO_DEPRECATED - User defined macros

DESCRIPTION
       User defined macros allow the programmer to control certain aspects of what is exposed by
       the OpenSSL headers.

       NOTE: to be effective, a user defined macro must be defined before including any header
       file that depends on it, either in the compilation command ("cc -DMACRO=value") or by
       defining the macro in source before including any headers.

       Other manual pages may refer to this page when declarations depend on user defined macros.

   The macros
       OPENSSL_API_COMPAT
           The value is a version number, given in one of the following two forms:

           "0xMNNFF000L"
               This is the form supported for all versions up to 1.1.x, where "M" represents the
               major number, "NN" represents the minor number, and "FF" represents the fix
               number, as a hexadecimal number.  For version 1.1.0, that's "0x10100000L".

               Any version number may be given, but these numbers are the current known major
               deprecation points, making them the most meaningful:

               "0x00908000L" (version 0.9.8)
               "0x10000000L" (version 1.0.0)
               "0x10100000L" (version 1.1.0)

               For convenience, higher numbers are accepted as well, as long as feasible.  For
               example, "0x60000000L" will work as expected.  However, it is recommended to start
               using the second form instead:

           "mmnnpp"
               This form is a simple decimal number calculated with this formula:

               major * 10000 + minor * 100 + patch

               where major, minor and patch are the desired major, minor and patch components of
               the version number.  For example:

               30000 corresponds to version 3.0.0
               10002 corresponds to version 1.0.2
               420101 corresponds to version 42.1.1

           If OPENSSL_API_COMPAT is undefined, this default value is used in its place: 30000

       OPENSSL_NO_DEPRECATED
           If this macro is defined, all deprecated public symbols in all OpenSSL versions up to
           and including the version given by OPENSSL_API_COMPAT (or the default value given
           above, when OPENSSL_API_COMPAT isn't defined) will be hidden.
