=head1 NAME

SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method

- choose a new TLS/SSL method

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 int SSL_CTX_set_ssl_version(SSL_CTX *ctx, SSL_METHOD *method);

 int SSL_set_ssl_method(SSL *s, SSL_METHOD *method);

 SSL_METHOD *SSL_get_ssl_method(SSL *ssl);

=head1 DESCRIPTION

SSL_CTX_set_ssl_version() sets a new default TLS/SSL B<method> for SSL objects

newly created from this B<ctx>. SSL objects already created with

L<SSL_new(3)|SSL_new(3)> are not affected, except when SSL_clear() is

being called.

SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<ssl>

object. It may be reset, when SSL_clear() is called.

SSL_get_ssl_method() returns a function pointer to the TLS/SSL method

set in B<ssl>.

=head1 NOTES

The available B<method> choices are described in

L<SSL_CTX_new(3)|SSL_CTX_new(3)>.

When SSL_clear() is called and no session is connected to an SSL object,

the method of the SSL object is reset to the method currently set in

the corresponding SSL_CTX object.

=head1 RETURN VALUES

The following return values can occur for SSL_CTX_set_ssl_version()

and SSL_set_ssl_method():

=over 4

=item 0

The new choice failed, check the error stack to find out the reason.

=item 1

The operation succeeded.

=head1 NAME

SSL_pending - obtain number of readable bytes buffered in an SSL object

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 int SSL_pending(SSL *ssl);

=head1 DESCRIPTION

SSL_pending() returns the number of bytes which are available inside

B<ssl> for immediate read.

=head1 NOTES

Data are received in blocks from the peer. Therefore data can be buffered

inside B<ssl> and are ready for immediate retrieval with

L<SSL_read(3)|SSL_read(3)>.

=head1 RETURN VALUES

The number of bytes pending is returned.

L<SSL_read(3)|SSL_read(3)>, L<ssl(3)|ssl(3)>
