From c941a980ccbd8def1d925fc5c69a22f40e1e5060 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Fri, 21 Jan 2000 15:07:55 +0000 Subject: Patch from Eric Norum to implement this: I'd like to propose a change to RTEMS task variables that I think would make them more useful. I think that it is early enough in their existence to still make changes to their API. 1) Change type from `int' to `void *'. 2) Add extra argument to task_variable_add -- if non-NULL, a pointer to a `destructor' function to be called when the task exits. This function would be called with that task's value of the task variable as its argument. In many cases, the `dtor' function could be `free'. rtems_status_code rtems_task_variable_add ( rtems_id tid, void **ptr, void (*dtor)(void *)); rtems_status_code rtems_task_variable_delete (rtems_id tid, void **ptr); This would be all we'd need to cleanly and efficiently support C++ per-thread exception information without dragging in all that POSIX API stuff. --- cpukit/score/include/rtems/score/thread.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'cpukit/score/include') diff --git a/cpukit/score/include/rtems/score/thread.h b/cpukit/score/include/rtems/score/thread.h index 0e2802bbac..ec48864a9f 100644 --- a/cpukit/score/include/rtems/score/thread.h +++ b/cpukit/score/include/rtems/score/thread.h @@ -93,8 +93,9 @@ struct rtems_task_variable_tt; struct rtems_task_variable_tt { struct rtems_task_variable_tt *next; - int *ptr; - int var; + void **ptr; + void *var; + void (*dtor)(void *); }; typedef struct rtems_task_variable_tt rtems_task_variable_t; -- cgit v1.2.3
