Miscellaneous I/O APIs - not supported (CrUn58)

Problem description

The identified Application Programming Interfaces (APIs) exist on Tru64 UNIX, and may or may not exist on HP-UX. If they do exist, it is in an unsupported or undocumented manner. Also, the use of these routines might result in unexpected behavior.

• createlabel - Creates a disk label structure for a disk device.

• forkpty - Creates a child process and establishes the slave pty as the child process' controlling terminal.

• openpty - Opens the pty master/slave pair and sets the terminal attributes of the slave pseudoterminal according to the specifications in the calling parameters.

• revoke - Voids all references to a file.

• async_daemon - Creates a local NFS asynchronous I/O server. (Note: The use of the async_daemon function is not supported in customer applications, and the interface is subject to change without notice. It is intended for use solely by the nfsiod(8) daemon.)

• exportfs - Allows the specified local file system to be mounted remotely by an NFS client.

• nfssvc - Creates a remote NFS server. (Note: The use of the nfssvc function is not supported in customer applications, and the interface is subject to change without notice. It is intended for use solely by the nfsd(8) daemon.)

• isfdtype - Tests a file descriptor for a specific file type.

• dbm_setpblksiz - Sets the page file block size.

• dbm_forder - Maintains key/content pairs in a database.
