LineCount contains the number of data lines stored (the data stored is line based, that is a data package
represents the data of a line).
Pad contains additional information to be stored.
Pad2 contains additional information to be stored.
The 64 Byte struct type below can be used to extract the file header.
struct FileHeader
{
char Signature[8];
char FileType[8];
LONG Version;
LONG LineCount;
char Pad[8];
char Pad2[32];
};
Data Structures
Following the header the data is stored as one or more data packages. The file header contains the num-
ber of data packages stored.
A data package contains a data header and the data itself.
The size of the data header is 12 Bytes.
The data header at the start of each data package contains the following information:
In PrevSize the size of the preceding data is stored, Size stores the size of the data contained in the suc-
ceeding data package and in TIME the timestamp of the data is stored.
The 12 Byte LineData struct type below can be used to extract the data header.
struct LineData
{
LONG PrevSize; // size of the data line before.
LONG Size; // size of the data line.
LONG TIME; // time of the data received.
}
