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.
