Persistent Data Segment

Overview

• Project template for a 64bit Windows executable
• Without C standard library (using only Windows functions)
• Therefore small executable size (4 kb)
• Across runs of the program, the contents of the variable persistent_data are preserved in the executable
• The executable can be renamed or moved between runs without losing the data
• The struct Peristent_Data can easily be extended by adding new members

Limitations

• The Peristent_Data struct should have a size >= 8 bytes
• Data can only be written back if no other instance of the program is running
• If the program is being renamed or moved while it is running, the changes of the persistent_data in this run will not be preserved (the executable will contain the last saved version in this case)
