gnutls_record_recv_seq: API function
NAMEgnutls_record_recv_seq - API function
- gnutls_session_t session
- is a gnutls_session_t structure.
- 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.
DESCRIPTIONThis 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.
RETURNSThe 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 .
