gnutls_record_recv_seq - API function
ssize_t gnutls_record_recv_seq(gnutls_session_t session, void * data, size_t data_size, unsigned char * seq);
is a gnutls_session_t type.
void * data
the buffer that the data will be read into
the number of requested bytes
unsigned char * seq
is the packets 64-bit sequence number. Should have space for 8 bytes.
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.
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 .
