This appendix describes TCP/IP-related application programming interfaces (APIs) that can be used under z/VSE. We distinguish between the following types of APIs:
There are socket functions for IPv4 and for IPv6. Also, there are some stack-dependent differences.
•Secure socket (SSL) APIs
The z/OS compatible GSK interface is supported by CSI’s SSL implementation and by OpenSSL. In addition, native OpenSSL functions can be used with the IJBSLVSE.OBJ file.
z/VSE and the IP stacks that are available for z/VSE ...
