Thanks Ben buddy! I ask this question because I noticed in the new release Notes of Palm OS, there are some announcement of multi-threaded support, right?
I have a further question about your reply below, > Also, applications can register for notifications where their routines will > be called while other programs are running. I have some experience on Palm programming. But I have no experience of what you mentioned above. Is that something like Inter-Process Communication and Synchronization approach (like IPC on Linux/UNIX)? Could you provide a formal URL to the related Palm developer document please? have a nice week, George ----- Original Message ---- From: Ben Combee <[EMAIL PROTECTED]> To: Palm Developer Forum <[email protected]> Sent: Monday, December 11, 2006 7:20:30 AM Subject: Re: multi-threaded application in Palm OS 5.2 On 12/10/06, Lin George <[EMAIL PROTECTED]> wrote: In my current understanding, Palm OS 5.2 only supports one application (process) one thread -- means each process could only have one thread. Is my understanding correct? Another quick question, if I am right for the previous point (one process can only have one thread), is it possible to do communication/information sharing between different processes on Palm OS 5.2? Like pipe similar communication, and other approaches? Is it possible to do cross-process synchronization, like mutex/lock/etc. You neither have multiple threads or multiple processes in standard Palm OS programming. To switch applications, the current one ends, then the system starts the new one. There is a limited background thread capability exposed through the sound stream APIs. Also, applications can register for notifications where their routines will be called while other programs are running. -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/ ____________________________________________________________________________________ Do you Yahoo!?
