Data Structures; File Headers And Data Structures For Individual File Types - Wavecom W74PC Manual

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
{
};

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.
DataHeader Data
12 Bytes n Bytes
A data package contains a data header and the data itself.
DataHeader
12 Bytes
The size of the data header is 12 Bytes.
The data header at the start of each data package contains the following information:
Size
PrevSize
4 Bytes 4 Bytes
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
{
}
