These functions, other than BIO_f_buffer(), are implemented as macros.
-Buffering BIOs implement BIO_gets() by using BIO_read() operations on the
+Buffering BIOs implement BIO_gets() by using BIO_read_ex() operations on the
next BIO in the chain. By prepending a buffering BIO to a chain it is therefore
possible to provide BIO_gets() functionality if the following BIOs do not
support it (for example SSL BIOs).
