NAME        top

       gnutls_handshake_set_max_packet_length - API function

SYNOPSIS        top

#include <gnutls/gnutls.h>void gnutls_handshake_set_max_packet_length(gnutls_session_tsession, size_tmax);

ARGUMENTS        top

       gnutls_session_t session                   is agnutls_session_ttype.       size_t max  is the maximum number.

DESCRIPTION        top

       This function will set the maximum size of all handshake messages.       Handshakes over this size are rejected withGNUTLS_E_HANDSHAKE_TOO_LARGEerror code.  The default value is       128kb which is typically large enough.  Set this to 0 if you do       not want to set an upper limit.       The reason for restricting the handshake message sizes are to       limit Denial of Service attacks.       Note that the maximum handshake size was increased to 128kb from       48kb in GnuTLS 3.5.5.
