Arguments
en
when set to DEF_ENABLED enables round-robin scheduling, and when set to DEF_DISABLED disables it.
dflt_time_quanta
is the default time quanta given to a task. This value is used when a task is created and you specify a value of 0 for the time quanta. In other words, if the user did not specify a non-zero for the task’s time quanta, this is the value that will be used. If passing 0 for this argument, µC/OS-III will assume a time quanta of 1/10 the tick rate. For example, if the tick rate is 1000 Hz and 0 is passed for dflt_time_quanta then, µC/OS-III will set the time quanta to 10 milliseconds.
p_err
is a pointer to a variable that is used to hold an error code:
OS_ERR_NONE
If the call is successful.
