 But from ssl.h, it seems that app_verify_callback prototype should be like
 int (*app_verify_callback)();
 Then how to pass SSL_CTX to app_verify_callback

Please grep for app_verify_callback in openssl/ssl/*.[ch] and see what I
mean. Please note, that func() in C means: no prototype, arguments are
not checked. (In C++, func() means no arguments - in C func(void).)

Best regards,
Lutz
PS. I wrote X509_STORE_CTX, not SSL_CTX, even though that does not matter
with respect to the discussion above.

I don't see a problem. The header files have the necessary
#ifdef  __cplusplus
extern C {
#endif

wrapping. So what you are going to supply is a callback
  int app_verify_callback(X509_STORE_CTX *ctx)
  {
  ...
  }

WARNING: Steve Henson put quite some effort into writing/extending OpenSSL's
internal verification mechanisms. I would strongly recommend to stay with
these routines unless you have a very special reason.

Best regards,
Lutz
