v GSK_V3_SIDCACHE_SIZE v GSK_LDAP_SERVER_PORT 4. The GSK_FD value is a socket descriptor that must have an address family of AF_INET or AF_INET6 and a socket type of SOCK_STREAM.

Parameters my_env_handle (Input) A pointer to the handle for the SSL environment to be closed. Authorities No authorization is required. 30 System i: Programming Secure Sockets APIs
Return Value gsk_environment_close() returns an integer. Possible values are: [GSK_OK] gsk_environment_close() was successful. [GSK_CLOSE_FAILED] An error occurred during close processing. [GSK_INVALID_HANDLE] The handle specified was not valid. [GSK_AS400_ERROR_INVALID_POINTER] my_env_handle pointer is not valid. [GSK_ERROR_IO] An error occurred in SSL processing, check the errno value. Error Conditions When the gsk_environment_close() API fails with return code [GSK_ERROR_IO], errno can be set to: [EINTR] Interrupted function call. [EDEADLK] Resource deadlock avoided. [ETERM] Operation terminated. If an errno is returned that is not in this list, look in “Errno Values for UNIX-Type Functions” on page 103 for a description of the errno. Error Messages Message ID Error Message Text CPE3418 E Possible APAR condition or hardware failure. CPF9872 E Program or service program &1 in library &2 ended. Reason code &3. CPFA081 E Unable to set return value or error code. Usage Notes 1. You should close all secure sessions using the SSL environment prior to doing the gsk_environment_close(). 2. If gsk_environment_close() is issued prior to all secure sessions being closed, the active secure sessions will continue to work. The resources for the SSL environment will not be freed up until after the last secure session closes. No new secure sessions will be allowed to start using the closed SSL environment.
