This section applies to non-Cygwin builds.
If you link with static OpenSSL libraries then you're expected to
- additionally link your application with WS2_32.LIB, ADVAPI32.LIB,
- GDI32.LIB and USER32.LIB. Those developing non-interactive service
- applications might feel concerned about linking with the latter two,
- as they are justly associated with interactive desktop, which is not
- available to service processes. The toolkit is designed to detect in
- which context it's currently executed, GUI, console app or service,
- and act accordingly, namely whether or not to actually make GUI calls.
- Additionally those who wish to /DELAYLOAD:GDI32.DLL and /DELAYLOAD:USER32.DLL
- and actually keep them off service process should consider
- implementing and exporting from .exe image in question own
- _OPENSSL_isservice not relying on USER32.DLL.
- E.g., on Windows Vista and later you could:
+ additionally link your application with WS2_32.LIB, GDI32.LIB,
+ ADVAPI32.LIB, CRYPT32.LIB and USER32.LIB. Those developing

{ DWORD sess;
