Function Overview

This section summarizes all the routines in the RL-FlashFS product. The functions are ordered according to the following categories:

The function format is same as that of the RL-RTX functions.

note

The RL-FlashFS library does not contain all the functions that are part of the RL-FlashFS product. The Library Reference section on each function mentions whether the function is in the library or not. If a function you want to use is not in the library, you must do one of the following:
- Include one of the provided RL-FlashFS source files that contains the function in your project. You can further customize the function.
- Provide your own function if the RL-FlashFS source files do not contain the function you require. This is usually the case when you want to use driver functions for a different hardware.
