0322 ; *
0322 ; * Returns : OS_NO_ERR if the requested task is resumed
0322 ; * OS_PRIO_INVALID if the priority you specify is higher that the maximum allowed
0322 ; * (i.e. >= OS_LOWEST_PRIO)
0322 ; * OS_TASK_RESUME_PRIO if the task to resume does not exist
0322 ; * OS_TASK_NOT_SUSPENDED if the task to resume has not been suspended
