Re: [Oorexx-devel] Question ad RexxSetHalt()
I see two reasons to return RXARI_NOT_FOUND from RexxSetHalt : either the interpreter is not started (not your case) or the threadid parameter is not registered with a RexxActivity (the procid parameter is not used) 0 is not a good value for threadid (I saw this value in one of your next mails). Jean-Louis 2011/8/3 Rony G. Flatscher rony.flatsc...@wu-wien.ac.at ** When issuing a RexxSetHalt() to halt all Rexx threads with size_t res=RexxSetHalt(getpid(), (pthread_t) 0); the result is 1, which according to rexxpg.pdf means:RXARI_NOT_FOUND 1 The target Rexx procedure was not found.. The documentation reads: 10.10.1.1. RexxSetHalt RexxSetHalt raises a HALT condition in a running Rexx program. retc = RexxSetHalt(ProcessId, ThreadId); 10.10.1.1.1. Parameters ProcessId (process_id_t) - input is the process ID of the target Rexx procedure. ProcessId is the application process that called the RexxStart function. ThreadId (thread_id_t) - input is the thread ID of the target Rexx procedure. ThreadId is the application thread that called the RexxStart function. If ThreadId=0, all the threads of the process are canceled. 10.10.1.1.2. Return Codes RXARI_OK 0 The function completed successfully. RXARI_NOT_FOUND 1 The target Rexx procedure was not found. RXARI_PROCESSING_ERROR 2 A failure in Rexx processing occurred. 10.10.1.1.3. Remarks This call is not processed if the target Rexx program is running with the RXHLT exit enabled. --- RexxSetHalt() is issued on another thread than the one that issued RexxStart(), but in the same process, of course. Is the ProcessId-related documentaiton wrong? Should it read thread instead of application process or is the API wrong or is there another reason one would get 1 as a result? ---rony -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.

Re: [Oorexx-devel] Howto end a Rexx interpreter instance in the following scenario ?
Could it be what you need ? context-Halt Raise a HALT condition on all threads associated with the interpreter instance Jean-Louis 2011/8/3 Rony G. Flatscher rony.flatsc...@wu-wien.ac.at ** The aforementioned Rexx server use case can be changed to be ended: if one ends the main thread (by not issuing a SysSleep() or doing a parse pull) and the message loop thread is running, then once the message loop thread ends (e.g. because of a Rexx condition, but also for other reasons) the program ends altogether. ---rony On 03.08.2011 20:53, Rony G. Flatscher wrote: The following scenario (a Rexx object running in the role of a server): - a Rexx program gets started, serving as a server, dispatching messages from clients - creates a message loop on a separate thread, dispatching messages from client - either calls SysSleep(someTime) or does parse pull x to keep the Rexx program alive Now, whenever a syntax error occurs while a Rexx message gets dispatched on the message loop thread (maybe even on another thread), it is not noticed by the main thread, it seems. In the message loop thread the Rexx condition causes it to be stopped and the message-loop thread goes away. However the main Rexx thread (either in SysSleep() or parse pull x) keeps on running, it seems. As reported in a previous message, RexxSetHalt(processId,0) returns 1 and does not work for ending all Rexx threads from the message loop thread, which knows that the state of the Rexx server application has become unstable, because of the syntax error that occurred on one of its dispatches. --- How is one able to end the threads of a Rexx interpreter instance? ---rony -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.
