Hooks can be defined per supported platform to allow for highly custom operations if needed.
|
|
This feature of MRAA should only be used by developers defining the board definitions, NOT an end user.
|
|
|
|
## Types of Hooks
|
|
|
|
** REPLACE **
|
|
Defining a replace function will entirely replace the associate function. This should only be done if your new function can handle everything the mraa function would normally.
|
|
|
|
** PRE **
|
|
Any functionality defined here will be performed when the main function is called.
|
|
|
|
** POST **
|
|
Any functionality perfomed here is done just before the normal function returns. All post functions will have passed into them the return value that would normally be returned.
|
