Deletes a thread referenced by the given handle.

BOOLEAN DeleteRtThread(
    RTHANDLE hThread    // handle for RT thread


A handle for the thread you want to delete. To delete the calling thread, use the value NULL_RTHANDLE.


If a thread deletes itself by calling this function and the containing process makes reference to any RSLs, the entry point of each RSL is called with a reason code of RSL_THREAD_DETACH in the context of the thread being deleted.

DeleteRtThread enables any thread currently within a region or waiting in a queue for a region to exit the region before being deleted. Deleting the thread counts toward both the object and thread limits for the containing process.

Any attempt to delete an interrupt thread results in an E_CONTEXT status code. Use ResetRtInterruptHandler instead.

Note: Normally, when a thread runs to completion, it executes the user code associated with RslMain() and RSL_THREAD_DETACH. Deleting another thread may result in that thread leaking resources. This is because the thread does not have a chance to execute its exit handlers. The leaked resources may be those allocated explicitly by the thread or by system code on behalf of the thread. A thread that deletes itself by calling DeleteRtThread does call RslMain().  If a thread returns from the initial thread function then it calls RslMain()  and deletes itself.

Return Values

Failure. To determine the status, call GetLastRtError.
