Data Fields | |
| TN_UWord * | stack_cur_pt |
| pointer to task's current top of the stack; Note that this field must be a first field in the struct, this fact is exploited by platform-specific routines. More... | |
| enum TN_ObjId | id_task |
| id for object validity verification. More... | |
| struct TN_ListItem | task_queue |
| queue is used to include task in ready/wait lists | |
| struct TN_Timer | timer |
| timer object to implement task waiting for timeout | |
| struct TN_ListItem * | pwait_queue |
| pointer to object's (semaphore, mutex, event, etc) wait list in which task is included for waiting | |
| struct TN_ListItem | create_queue |
| queue is used to include task in creation list (currently, this list is used for statistics only) | |
| struct TN_ListItem | mutex_queue |
| list of all mutexes that are locked by task | |
| struct TN_ListItem | deadlock_list |
| list of other tasks involved in deadlock. More... | |
| TN_UWord * | stack_low_addr |
| – lowest address of stack. More... | |
| TN_UWord * | stack_high_addr |
| – Highest address of stack. More... | |
| TN_TaskBody * | task_func_addr |
pointer to task's body function given to tn_task_create() | |
| void * | task_func_param |
pointer to task's parameter given to tn_task_create() | |
| int | base_priority |
| base priority of the task (actual current priority may be higher than base priority because of mutex) | |
| int | priority |
| current task priority | |
| enum TN_TaskState | task_state |
| task state | |
| enum TN_WaitReason | task_wait_reason |
reason for waiting (relevant if only task_state is WAIT or WAIT+SUSPEND) | |
| enum TN_RCode | task_wait_rc |
| waiting result code (reason why waiting finished) | |
| int | tslice_count |
| time slice counter | |
| union { | |
| struct TN_EGrpTaskWait eventgrp | |
| fields specific to tn_eventgrp.h | |
| struct TN_DQueueTaskWait dqueue | |
| fields specific to tn_dqueue.h | |
| struct TN_FMemTaskWait fmem | |
| fields specific to tn_fmem.h | |
| } | subsys_wait |
| subsystem-specific fields that are used while task waits for something. More... | |
| const char * | name |
| Task name for debug purposes, user may want to set it by hand. | |
| struct _TN_TaskProfiler | profiler |
Profiler data, available if only TN_PROFILER is non-zero. | |
| unsigned | priority_already_updated: 1 |
| Internal flag used to optimize mutex priority algorithms. More... | |
| unsigned | waited: 1 |
Flag indicates that task waited for something This flag is set automatially in _tn_task_set_waiting() Must be cleared manually before calling any service that could sleep, if the caller is interested in the relevant value of this flag. More... | |
| TN_UWord* TN_Task::stack_cur_pt |
pointer to task's current top of the stack; Note that this field must be a first field in the struct, this fact is exploited by platform-specific routines.

| enum TN_ObjId TN_Task::id_task |
id for object validity verification.
This field is in the beginning of the structure to make it easier to detect memory corruption. For struct TN_Task, we can't make it the very first field, since stack pointer should be there.
Definition at line 341 of file tn_tasks.h.
| struct TN_ListItem TN_Task::deadlock_list |
list of other tasks involved in deadlock.
This list is non-empty only in emergency cases, and it is here to help you fix your bug that led to deadlock.

| TN_UWord* TN_Task::stack_low_addr |
– lowest address of stack.
It is independent of architecture: it's always the lowest address (which may be actually origin or end of stack, depending on the architecture)
Definition at line 375 of file tn_tasks.h.
| TN_UWord* TN_Task::stack_high_addr |
– Highest address of stack.
It is independent of architecture: it's always the highest address (which may be actually origin or end of stack, depending on the architecture)
Definition at line 379 of file tn_tasks.h.
| union { ... } TN_Task::subsys_wait |
subsystem-specific fields that are used while task waits for something.
Do note that these fields are grouped by union, so, they must not interfere with each other. It's quite ok here because task can't wait for different things.
| unsigned TN_Task::priority_already_updated |
Internal flag used to optimize mutex priority algorithms.
For the comments on it, see file tn_mutex.c, function _mutex_do_unlock().

| unsigned TN_Task::waited |
Flag indicates that task waited for something This flag is set automatially in _tn_task_set_waiting() Must be cleared manually before calling any service that could sleep, if the caller is interested in the relevant value of this flag.
