Problem description

The _POSIX_ACL_EXTENDED, _POSIX_ASYNC_IO, and _POSIX_PRIO_IO variables are available on Tru64 UNIX but not on HP-UX.

  • _POSIX_ACL_EXTENDED (_PC_ACL_EXTENDED) - The Access Control List (ACL) processing status value for the file. The return indicates if an ACL can be set on the file and if ACL processing is enabled for the file. The return does not indicate if an ACL is set on the file.

  • _POSIX_ASYNC_IO (_PC_ASYNC_IO) - Asynchronous I/O may be performed for the specified file. Returns a value other than -1 on all applicable files. (On Tru64 UNIX systems, asynchronous I/O is supported for all applicable files.)

  • _POSIX_PRIO_IO (_PC_PRIO_IO) - Prioritized input and output operations may be performed on the specified file. Returns -1. (Prioritized I/O is not available on Tru64 UNIX systems.)

Support for _POSIX_ASYNC_IO and _POSIX_PRIO_IO is planned for a future release of HP-UX.
