222 Definitions of OPENSSL_EXPORT and OPENSSL_IMPORT, to define and declare
223 DLL exports and imports for compilers under Win32. These are a little
224 more complicated to use. Basically, for any library that exports some
225 global variables, the following code must be present in the header file
226 that declares them, before OPENSSL_EXTERN is used:
228 #ifdef SOME_BUILD_FLAG_MACRO
229 # undef OPENSSL_EXTERN
230 # define OPENSSL_EXTERN OPENSSL_EXPORT

234 have some generally sensible values, and for OPENSSL_EXTERN to have the
235 value OPENSSL_IMPORT.
