64 Calling BIO_reset() on a read write memory BIO clears any data in it if the
66 pointer to the state it was just after the last write was performed and the
67 data can be read again. On a read only BIO it similarly restores the BIO to
68 its original state and the read only data can be read again.
79 positive return value B<v> should be set to a negative value, typically -1.
95 if B<len> is -1 then the B<buf> is assumed to be nul terminated and its
96 length is determined by B<strlen>. The BIO is set to a read only state and
109 L<BIO_set_write_buf_size(3)> is called on it. In such case the write buffer

127 The other supported sequence is to start with a read write BIO then temporarily
128 switch it to read only and call BIO_reset() on the read only BIO immediately
129 before switching it back to read write. Before the BIO is freed it must be
130 switched back to the read write mode.
