215 Definitions of OPENSSL_EXPORT and OPENSSL_IMPORT, to define and declare
216 DLL exports and imports for compilers under Win32. These are a little
217 more complicated to use. Basically, for any library that exports some
218 global variables, the following code must be present in the header file
219 that declares them, before OPENSSL_EXTERN is used:
221 #ifdef SOME_BUILD_FLAG_MACRO
222 # undef OPENSSL_EXTERN
223 # define OPENSSL_EXTERN OPENSSL_EXPORT
226 The default is to have OPENSSL_EXPORT, OPENSSL_IMPORT and OPENSSL_GLOBAL
227 have some generally sensible values, and for OPENSSL_EXTERN to have the
228 value OPENSSL_IMPORT.
