-
- #define BIO_set_callback(b,cb)		((b)->callback=(cb))
- #define BIO_get_callback(b)		((b)->callback)
- #define BIO_set_callback_arg(b,arg)	((b)->cb_arg=(char *)(arg))
- #define BIO_get_callback_arg(b)		((b)->cb_arg)
-
- long BIO_debug_callback(BIO *bio,int cmd,const char *argp,int argi,
-	long argl,long ret);
-
- typedef long callback(BIO *b, int oper, const char *argp,
-			int argi, long argl, long retvalue);

-=head1 DESCRIPTION
-
-BIO_set_callback() and BIO_get_callback() set and retrieve the BIO callback,
-they are both macros. The callback is called during most high level BIO
-operations. It can be used for debugging purposes to trace operations on
-a BIO or to modify its operation.
-
-BIO_set_callback_arg() and BIO_get_callback_arg() are macros which can be
-used to set and retrieve an argument for use in the callback.
-
-BIO_debug_callback() is a standard debugging callback which prints
-out information relating to each BIO operation. If the callback
-argument is set if is interpreted as a BIO to send the information
-to, otherwise stderr is used.
-
-callback() is the callback function itself. The meaning of each
-argument is described below.
-
-The BIO the callback is attached to is passed in B<b>.
-
-B<oper> is set to the operation being performed. For some operations
-the callback is called twice, once before and once after the actual
-operation, the latter case has B<oper> or'ed with BIO_CB_RETURN.
-
-The meaning of the arguments B<argp>, B<argi> and B<argl> depends on
-the value of B<oper>, that is the operation being performed.
-
-B<retvalue> is the return value that would be returned to the
-application if no callback were present. The actual value returned
-is the return value of the callback itself. In the case of callbacks
-called before the actual BIO operation 1 is placed in retvalue, if
-the return value is not positive it will be immediately returned to
-the application and the BIO operation will not be performed.
-
-The callback should normally simply return B<retvalue> when it has
-finished processing, unless if specifically wishes to modify the
-value returned to the application.

-
-=over 4
-
-=item B<BIO_free(b)>
-
-callback(b, BIO_CB_FREE, NULL, 0L, 0L, 1L) is called before the
-free operation.
-
-=item B<BIO_read(b, out, outl)>
-
-callback(b, BIO_CB_READ, out, outl, 0L, 1L) is called before
-the read and callback(b, BIO_CB_READ|BIO_CB_RETURN, out, outl, 0L, retvalue)
-after.
-
-=item B<BIO_write(b, in, inl)>
-
-callback(b, BIO_CB_WRITE, in, inl, 0L, 1L) is called before
-the write and callback(b, BIO_CB_WRITE|BIO_CB_RETURN, in, inl, 0L, retvalue)
-after.
-
-=item B<BIO_gets(b, out, outl)>
-
-callback(b, BIO_CB_GETS, out, outl, 0L, 1L) is called before
-the operation and callback(b, BIO_CB_GETS|BIO_CB_RETURN, out, outl, 0L, retvalue)
-after.
-
-=item B<BIO_puts(b, in)>
-
-callback(b, BIO_CB_WRITE, in, 0, 0L, 1L) is called before
-the operation and callback(b, BIO_CB_WRITE|BIO_CB_RETURN, in, 0, 0L, retvalue)
-after.
-
-=item B<BIO_ctrl(BIO *b, int cmd, long larg, void *parg)>
-
-callback(b,BIO_CB_CTRL,parg,cmd,larg,1L) is called before the call and
-callback(b,BIO_CB_CTRL|BIO_CB_RETURN,parg,cmd, larg,ret) after.
