Is the C SDK for 64bit Linux (CentOS) available?

Background:

We are porting old legacy code from Solaris 32bit to Linux 64bit. This application contains the old Reuters ssl implementation on Solaris 32bit OS. Hence, we are looking for C SDK in 64Bit for CentOS.

Details:

Below is the function extract from our old ssh.h
