Real-Time OS Functions may be defined using the __task function attribute:
void funcname (void) __task
Where:
| funcname | is the name of the task function. |
| __task | indicates the function is a task function. |
The __task attribute affects the generated code of the function as follows:
- The function does not include a prolog or an epilog. Therefore, it is not possible to call the function from other routines. Instead, the Real-Time Operating System must save and restore all CPU register context.
