Features Planned for a Future Release
This section describes OSF DCE and HP DCE features that will be
supported in future releases of HP DCE.
• 64-bit libraries to support DCE 64-bit application development
• Kernel-threaded (POSIX 1003.1c) DCE
• LDAP NSI version for 10.20 and 11.0
• Improved scalibility, robustness, and availability
• Improved administration and configuration
Future Support for POSIX 1003.1c Threads
CMA applications are likely to migrate from Draft 4 of the POSIX
threads standard to the final, ratified 1003.1c standard for kernel
threads. This migration will result in source incompatibility, and it is
recommended that application developers plan now for this transition.
HP plans to preserve binary compatibility. However, developers can
prepare for this change as follows:
1. Isolate new threads API usage to macros or wrapper APIs.
2. Minimize the use of signals, and use only POSIX semantics when
programming with signals.
For example, we recommed that thjreaded applications use only the
functions sigaction(), sigprocmask(), and sigwait().
