* Name: task_starthook |
|
* |
|
* Description: |
|
* Configure a start hook... a function that will be called on the thread |
|
* of the new task before the new task's main entry point is called. |
|
* The start hook is useful, for example, for setting up automatic |
|
* configuration of C++ constructors. |
|
* |
|
* Inputs: |
|
* tcb - The new, unstarted task task that needs the start hook |
|
* starthook - The pointer to the start hook function |
|
* arg - The argument to pass to the start hook function. |
|
* |
|
* Return: |
|
* None |
