|

* All user-facing data types of the task pool library can be initialized using
|

* one of the following.
|

*
|
||||
* @warning Failure to initialize a task pool data type with the appropriate initializer
|
||||
* may result in a runtime error!
|
||||
* @note The initializers may change at any time in future versions, but their
|
||||
* names will remain the same.
|
||||
*
|
||||
* <b>Example</b>
|
||||
* @code{c}
|
||||
*
|
||||
* IotTaskPool_t * pTaskPool;
|

*
|
