Create a new thread, and start it executing the specified function.
- Parameters:
-
task function to be executed by this thread. argument pointer that is passed to the thread function as start argument. (default: NULL). priority initial priority of the thread function. (default: osPriorityNormal). stack_size stack size (in bytes) requirements for the thread function. (default: DEFAULT_STACK_SIZE). stack_pointer pointer to the stack area to be used by this thread (default: NULL).

Member Function Documentation
| osPriority get_priority | ( | ) |
Get priority of an active thread \ return current priority value of the thread function.
Definition at line 34 of file Thread.cpp.
| osThreadId gettid | ( | ) | [static] |
Get the thread id of the current running thread.
- Returns:
- thread ID for reference by other functions or NULL in case of error.
Definition at line 54 of file Thread.cpp.
| osStatus set_priority | ( | osPriority | priority ) |
Set priority of an active thread
- Parameters:
-
priority new priority value for the thread function.
- Returns:
- status code that indicates the execution status of the function.
Definition at line 30 of file Thread.cpp.
| int32_t signal_set | ( | int32_t | signals ) |
Set the specified Signal Flags of an active thread.
- Parameters:
-
signals specifies the signal flags of the thread that should be set.
- Returns:
- previous signal flags of the specified thread or 0x80000000 in case of incorrect parameters.
Definition at line 38 of file Thread.cpp.
| osEvent signal_wait | ( | int32_t | signals, |
| uint32_t | millisec = osWaitForever |
||
| ) | [static] |
Wait for one or more Signal Flags to become signaled for the current RUNNING thread.
- Parameters:
-
signals wait until all specified signal flags set or 0 for any single signal flag. millisec timeout value or 0 in case of no time-out. (default: osWaitForever).
- Returns:
- event flag information or error code.
Definition at line 42 of file Thread.cpp.
| osStatus terminate | ( | ) |
Terminate execution of a thread and remove it from Active Threads
- Returns:
- status code that indicates the execution status of the function.
Definition at line 26 of file Thread.cpp.
| osStatus wait | ( | uint32_t | millisec ) | [static] |
Wait for a specified time period in millisec:
- Parameters:
-
millisec time delay value
- Returns:
- status code that indicates the execution status of the function.
Definition at line 46 of file Thread.cpp.
| osStatus yield | ( | ) | [static] |
Pass control to next thread that is in state READY.
- Returns:
- status code that indicates the execution status of the function.
Definition at line 50 of file Thread.cpp.
