hi Ger Hobbelt
thank you soooooooo much .
your answer 2) solve my problem well.
because there exists libeay32.dll ,ssleay32.dll ,my own dll and my application.
my own dll call libeay32.dll and ssleay32.dll. And my application call my own
dll.
according to Ger Hobbelt's suggestion 2), firstly I used a tool to analyse the
exports functions of libeay32.dll ,ssleay32.dll and my own dll. I found that
dll exports functions don't contain OPENSSL_Applink() function. Also I look up
the source code of Uplink.c which call OPENSSL_Applink() function. Uplink.c
use <h=GetModuleHandle(NULL)> to get a handle h, and then use
<applink=(void**(*)())GetProcAddress(h,"OPENSSL_Applink")> to got the address
of OPENSSL_Applink() . when I use libeay32.dll ,ssleay32.dll in my application
, this handle h will point to the application but not my own dll.
So I should add applink.c to my application as a part of my application source
code , never add it to my own dll source code.
