SSL_CTX_set_read_ahead(3)                    OpenSSL                    SSL_CTX_set_read_ahead(3)



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

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)

DESCRIPTION
       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 x bytes are currently
       required by OpenSSL, but y bytes are available from the underlying BIO (where y > x), then
       OpenSSL will read all y bytes into its buffer (providing that the buffer is large enough)
       if reading ahead is on, or x bytes otherwise. The parameter yes or 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.

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.

RETURN VALUES
       SSL_get_read_ahead and SSL_CTX_get_read_ahead return 0 if reading ahead is off, and non
       zero otherwise.
