tSNMPD	106fd8	b1eb80	46	PEND+T	1bcda8	b1d5b0	3d0004	1968

These are the descriptions of the information in each column:

•Name—name of the task

•Entry—entry point; the top-level function of the task

•TID—task identifier; the task control block

•PRI—task priority; a low number means a high priority

•Status—status of the task; five statuses are possible:

–Pend—The task is in an inactive waiting state.

–Pend+T—The task is waiting, but it has a timeout value for the length of time it will wait for an external event to wake the task and start it.

–Suspend—The task will not begin until some external event occurs.

–Ready—The task is ready to run.

–Delay—The task issued a delay command and will not run until the delay time elapses.

•PC—program counter; a memory address of the task

•SP—stack pointer; another memory address of the task

•ERRNO—error number; the latest error reported by any function called by the task

•Delay—delay interval in system clock-ticks (1/52 second) that must elapse before the task runs
