Lubomir Rintel 23f5908ac7 POD: Fix item numbering
Newer pod2man considers =item [1-9] part of a numbered list, while =item
0 starts an unnumbered list. Add a zero effect formatting mark to override
this.

number

=head1 NAME
SSL_set_fd - connect the SSL object with a file descriptor
=head1 SYNOPSIS
#include <openssl/ssl.h>
int SSL_set_fd(SSL *ssl, int fd);
int SSL_set_rfd(SSL *ssl, int fd);
int SSL_set_wfd(SSL *ssl, int fd);
=head1 DESCRIPTION
SSL_set_fd() sets the file descriptor B<fd> as the input/output facility
for the TLS/SSL (encrypted) side of B<ssl>. B<fd> will typically be the
socket file descriptor of a network connection.
When performing the operation, a B<socket BIO> is automatically created to
interface between the B<ssl> and B<fd>. The BIO and hence the SSL engine
inherit the behaviour of B<fd>. If B<fd> is non-blocking, the B<ssl> will
also have non-blocking behaviour.
If there was already a BIO connected to B<ssl>, BIO_free() will be called
(for both the reading and writing side, if different).
SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only
for the read channel or the write channel, which can be set independently.
=head1 RETURN VALUES
The following return values can occur:
=over 4
=item Z<>0
The operation failed. Check the error stack to find out why.
=item Z<>1
The operation succeeded.
