NAME         top

       gnutls_record_recv_seq - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_recv_seq(gnutls_session_t session, void * data,
       size_t data_size, unsigned char * seq);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       void * data the buffer that the data will be read into

       size_t data_size
                   the number of requested bytes

       unsigned char * seq
                   is the packet's 64-bit sequence number. Should have space
                   for 8 bytes.

DESCRIPTION         top

       This function is the same as gnutls_record_recv(), except that it
       returns in addition to data, the sequence number of the data.  This
       is useful in DTLS where record packets might be received
       out-of-order. The returned 8-byte sequence number is an integer in
       big-endian format and should be treated as a unique message

RETURNS         top

       The number of bytes received and zero on EOF.  A negative error code
       is returned in case of an error.  The number of bytes received might
       be less than  data_size .
