Format of '*.edf.seizures' (CHB-MIT database)

From the code that Alex and Walter had provided, I do know that byte_array(39) and byte_array(42) shows us with the seizure starting time; byte_array(50) is the length of seizure, but I have no idea about the meaning the others.

      file_descriptor = fopen(annotation_file_location);

      byte_array = fread(file_descriptor);

      seizure_start_time_offset_in_seconds = bin2dec(strcat(dec2bin(byte_array(39)),dec2bin(byte_array(42))));

      seizure_length_in_seconds = byte_array(50);

Please help me.

May I have more detail about the meaning of every single byte from .edf.seizures files?

I did not find a description of the file format.
