=head1 DESCRIPTION
The BIO_push() function appends the BIO B<append> to B<b>, it returns
B<b>.
BIO_push() pushes I<b> on I<next>.
If I<b> is NULL the function does nothing and returns I<next>.
Otherwise it prepends I<b>, which may be a single BIO or a chain of BIOs,
to I<next> (unless I<next> is NULL).
It then makes a control call on I<b> and returns I<b>.
BIO_pop() removes the BIO B<b> from a chain and returns the next BIO
in the chain, or NULL if there is no next BIO. The removed BIO then
becomes a single BIO with no association with the original chain,
it can thus be freed or attached to a different chain.
BIO_pop() removes the BIO I<b> from any chain is is part of.
If I<b> is NULL the function does nothing and returns NULL.
Otherwise it makes a control call on I<b> and
returns the next BIO in the chain, or NULL if there is no next BIO.
The removed BIO becomes a single BIO with no association with
the original chain, it can thus be freed or be made part of a different chain.
BIO_set_next() replaces the existing next BIO in a chain with the BIO pointed to
by B<next>. The new chain may include some of the same BIOs from the old chain

=head1 NOTES
On Windows, a socket handle is a 64-bit data type (UINT_PTR), which leads to a
compiler warning (conversion from 'SOCKET' to 'int', possible loss of data) when
passing the socket handle to SSL_set_*fd(). For the time being, this warning can
safely be ignored, because although the Microsoft documentation claims that the
upper limit is INVALID_SOCKET-1 (2^64 - 2), in practice the current socket()
implementation returns an index into the kernel handle table, the size of which
is limited to 2^24.
