what is "for semantic compatibility" means?

[陈逸飞]

Dear author:
I see
SSL_library_init();
SSL_load_error_strings();
in the file tlssimple.c
what is the comment "dummy functions ... for semantic compatibility only" means?

These are function that do absolutely nothing, just to be able to compile simple examples written for libssl. You don't need to call them in newly written code.
