Function of the "offset" term in pstorage

[Anton Maes]

I've been reading through the documentation for pstorage but there's one term I don't understand

devzone.nordicsemi.com/.../a00131.html

What is the purpose of offset?

[ting²]

Neither do I . Do you find the answer?

You use offest if you don't want to do a pstorage operation a complete block, but only a part of it. If you have a block of 16 bytes you can do an operation on the 12 last bytes by using an offset of 4 bytes.
