Overview of newlib support (newlib is from CYGNUS)
|
||||
Each task can have its own libc state including:
|
||||
open stdio files
|
||||
strtok
|
||||
multi precision arithmetic state
|
||||
etc.
|
||||
|
||||
This is implemented by a reentrancy data structure for each task.
|
||||
|
||||
When a task is "started" (in RTEMS sense) the reentrancy structure
|
||||
is allocated. Its address is stored in notepad[NOTEPAD_LAST].
|
||||
|
||||
When task is switched to, the value of global variable _impure_ptr
|
||||
is changed to the value of the new tasks reentrancy structure.
|
||||
|
||||
When a task is deleted
|
||||
atexit() processing (for that task) happens
|
||||
task's stdio buffers are flushed
|
||||
|
||||
When exit(3) is called
|
||||
calling task's atexit processing done
|
||||
global libc state atexit processing done
|
||||
(this will include any atexit routines installed by drivers)
|
||||
executive is shutdown
|
||||
causes a context switch back to bsp land
|
||||
|
||||
|
||||
NOTE:
|
||||
libc extension are installed by bsp_libc_init()
|
||||
iff we are using clock interrupts.
|
||||
This hack is necessary to allow the tmtests to avoid
|
||||
timing the extensions.

* Function: _exit

* Created: 94/12/10

*
|

* Description:
|

* Called from exit() after it does atexit() processing and stdio fflush's
|
||||
*
|
||||
* called from bottom of exit() to really delete the task.
|
||||
* If we are using reentrant libc, then let the delete extension
|
||||
* do all the work, otherwise if a shutdown is in progress,
|
||||
* then just do it.
|

*
|
||||
* Parameters:
|
||||
* exit status
|

*
|

* Returns:
|
