Getting informed by changes

[Lordi Proctor]

Hello all! :)

I've several users with different Handles each user. Now I want to know if and when any of this user have made changes to a table.

For example:
--------------
User A is reading content from the table T
User B made changes to table T (different Handle!)
User A should be now able to know that B had made changes, so that he can update his content (display)

Is there any way to do this? In the C-API I couldn't found any useful function. Does InnoDB provides any functions for this problem?

Thanks & Greetz,

Lordi
