NAME

6       gnutls_record_recv_seq - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       ssize_t  gnutls_record_recv_seq(gnutls_session_t  session, void * data,
12       size_t data_size, unsigned char * seq);
13

ARGUMENTS

15       gnutls_session_t session
16                   is a gnutls_session_t type.
17
18       void * data the buffer that the data will be read into
19
20       size_t data_size
21                   the number of requested bytes
22
23       unsigned char * seq
24                   is the packet's 64-bit sequence number. Should  have  space
25                   for 8 bytes.
26

DESCRIPTION

28       This  function  is the same as gnutls_record_recv(), except that it re‐
29       turns in addition to data, the sequence number of the  data.   This  is
30       useful in DTLS where record packets might be received out-of-order. The
31       returned 8-byte sequence number is an integer in big-endian format  and
32       should be treated as a unique message identification.
33

RETURNS

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