* Description:
|
|
* Configure a newly allocated TCB so that it will inherit
|
|
* file descriptors and streams from the parent task.
|
|
*
|
|
* Input Parameters:
|
|
* tcb - tcb of the new task.
|
|
* actions - The spawn file actions
|
|
* cloexec - Perform O_CLOEXEC on setup task files
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) is returned on success; A negated errno value is returned on
|
|
* failure.
