=head1 DESCRIPTION
BIO_meth_free() destroys a B<BIO_METHOD> structure and frees up any memory
associated with it.
-BIO_meth_get_write() and BIO_meth_set_write() get and set the function used for
-writing arbitrary length data to the BIO respectively. This function will be
-called in response to the application calling BIO_write(). The parameters for
-the function have the same meaning as for BIO_write().
-
-BIO_meth_get_read() and BIO_meth_set_read() get and set the function used for
-reading arbitrary length data from the BIO respectively. This function will be
-called in response to the application calling BIO_read(). The parameters for the
-function have the same meaning as for BIO_read().
+BIO_meth_get_write_ex() and BIO_meth_set_write_ex() get and set the function
+used for writing arbitrary length data to the BIO respectively. This function
+will be called in response to the application calling BIO_write_ex() or
+BIO_write(). The parameters for the function have the same meaning as for
+BIO_write_ex(). Older code may call BIO_meth_get_write() and
+BIO_meth_set_write() instead. Applications should not call both
+BIO_meth_set_write_ex() and BIO_meth_set_write() or call BIO_meth_get_write()
+when the function was set with BIO_meth_set_write_ex().

BIO_meth_get_puts() and BIO_meth_set_puts() get and set the function used for
writing a NULL terminated string to the BIO respectively. This function will be
