Memory Levels

2 Modifying Files on the FFS

Operations that require writing to the FFS should almost always check "disk space" both before and after the operation. There are three defined levels of available disk space on the device. These levels are:

• Not full (more than 50kb available)
• Nearly full (between 25 and 50kb available)
• Full (less than 25 kb available)

You can check for these conditions by using the following constants:

• FOAM_DISK_SPACE_NEARLY_FULL_LEVEL
• FOAM_DISK_SPACE_FULL_LEVEL

FFS checking is usually needed at the following times:

• Writing files to disk
• Engaging in an operation that consumes memory
