E Digital Proprietary Interface Routines: CMA

This appendix provides detailed descriptions of the (cma) routines that are part of the Digital proprietary interfaces to DECthreads.

Note

In future releases, the cma interface used with DECthreads will continue to exist and be supported in the OpenVMS operating system, but it will no longer be documented or enhanced. Therefore, Digital recommends that you port your cma-based application to the IEEE Std 1003.1c-1995, POSIX System Application Program Interface provided by DECthreads. In addition to providing cma routine documentation, this appendix also gives hints about migrating your application from using the cma interface to using the new POSIX 1003.1c pthread interface.

It may be beneficial to save the previous version of this guide if you intend to support an application written using cma for many years.

To indicate errors, the cma routines raise exceptions. See Section E.4 for exception descriptions.
