NAME

       gnutls_record_recv_seq - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

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

ARGUMENTS

       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

       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 identification.

RETURNS

       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 .

SINCE

       3.0
