RTEMS ITRON 3.0 API User's Guide
The sta_tsk directive starts the task specified by tskid. Specifically, it changes the state of the task specified by tskid from DORMANT into RUN/READY. This enables the task to compete, based on its current priority, for the processor and other system resources. Any actions, such as suspension or change of priority, performed on a task prior to starting it are nullified when the task is started.
Stacd can be used to specify parameters to be passed to the task when it is started. This parameter can be read by the task being started, and may be used for transmitting simple messages.
The task priority on starting the task is given by the initial task priority parameter (itskpri) specified when the task was created.
Start request is not queued in this this system call. In other words, if this system call is issued when the target task is not in DORMANT state, the system call will be ignored, and an E_OBJ error returned to the issuing task.
If cre_tsk [level EN] is not implemented on a system, tasks are created statically when the system is started. Parameters required for creating a task, such as task starting address (task) and initial task priority (itskpri) are also specified statically at system startup.
