+=head1 NAME
+SSL_CTX_set_read_ahead, SSL_CTX_set_default_read_ahead, SSL_CTX_get_read_ahead,
+SSL_CTX_get_default_read_ahead, SSL_set_read_ahead, SSL_get_read_ahead
+- manage whether to read as many input bytes as possible
+=head1 SYNOPSIS
+ #include <openssl/ssl.h>
+ int SSL_get_read_ahead(const SSL *s);
+ void SSL_set_read_ahead(SSL *s, int yes);
+ #define SSL_CTX_get_default_read_ahead(ctx)
+ #define SSL_CTX_set_default_read_ahead(ctx,m)
+ #define SSL_CTX_get_read_ahead(ctx)
+ #define SSL_CTX_set_read_ahead(ctx,m)
+SSL_CTX_set_read_ahead() and SSL_set_read_ahead() set whether we should read as
+many input bytes as possible (for non-blocking reads) or not. For example if
+B<x> bytes are currently required by OpenSSL, but B<y> bytes are available from
+the underlying BIO (where B<y> > B<x>), then OpenSSL will read all B<y> bytes
+into its buffer (providing that the buffer is large enough) if reading ahead is
+on, or B<x> bytes otherwise. The parameter B<yes> or B<m> should be 0 to ensure
+reading ahead is off, or non zero otherwise.
+SSL_CTX_set_default_read_ahead is a synonym for SSL_CTX_set_read_ahead, and
+SSL_CTX_get_default_read_ahead is a synonym for SSL_CTX_get_read_ahead.
+SSL_CTX_get_read_ahead() and SSL_get_read_ahead() indicate whether reading
+ahead has been set or not.
+=head1 NOTES
+These functions have no impact when used with DTLS. The return values for
+SSL_CTX_get_read_head() and SSL_get_read_ahead() are undefined for DTLS.
+SSL_get_read_ahead and SSL_CTX_get_read_ahead return 0 if reading ahead is off,
+and non zero otherwise.
