This structure contains the data defining the header for one data set stored on the data file.
- Warning
- Only the master process actually performs the read/write operations. In case of reading the master reads the data and then broadcasts to every process. However, in case of writing every other routine that is accessing the same file as that which was written into by this object must take this into account: the current position in the file will be different for other process than the master (the other ones will be typically "behind").
◆ print()
| procedure data_file_gbl::data_header_obj::print |
Prints the header data into stdout.
◆ read()
| procedure data_file_gbl::data_header_obj::read |
Reads-in the header data given the starting position of the header in the file and the unit number.
◆ write()
| procedure data_file_gbl::data_header_obj::write |
Writes the header data into the unit number at a position given by the member variable header_pos.
◆ first_record
| integer data_file_gbl::data_header_obj::first_record = -1 |
Positions, within the file storing the data, of the first and the last record for this data set. The positions are given in bytes.
◆ header_pos
| integer data_file_gbl::data_header_obj::header_pos = -1 |
Position, within the file storing the data, of the first line of the header information.
◆ last_record
| integer data_file_gbl::data_header_obj::last_record = -1 |
◆ name
| character(line_len) data_file_gbl::data_header_obj::name = no_header |
Description (name) for the stored data.
◆ next_data
| integer data_file_gbl::data_header_obj::next_data = -1 |
Position, within the file storing the data, of the header for the header for the next data set stored on the file.
