4 Not every object in Solaris 2 and Solaris 7can have names composed of
arbitrary characters. The names of the following objects must be composed
of ASCII characters:
– User names, group name, and passwords
– System name
– Names of printers and special devices
– Names of terminals (/ dev/tty* )
– Process ID numbers
– Message queues, semaphores, and shared memory labels.
– The following may be composed of ISO Latin-1 or EUC characters:
– File names
– Directory names
– Command names
– Shell variables and environmental variable names
– Mount points for file systems
– NIS key names and domain names
4 The names of NFS shared files should be composed of ASCII characters.
Although files and directories may have names and contents composed of
characters from non-ASCII code sets, using only the ASCII codeset allows
NFS mounting across any machine, regardless of localization. For the
commands and utilities that are CSI enabled, all can handle single-byte and
multi-byte locales released in 2.6. For applications to get full support of
internationalization services, dynamic binding has to be applied. Statically
bound programs will only get support for C and POSIX locales.
Interface Stability
Sun often provides developers with early access to new technologies, which
allows developers to evaluate with them as soon as possible. Unfortunately,
new technologies are prone to changes and standardization often results in
interface incompatibility from previous versions.
To make reasonable risk assessments, developers need to know how likely an
interface is to change in future releases. To aid developers in making these
assessments, interface stability information is included on some manual pages
for commands, entry-points, and file formats.
The more stable interfaces can safely be used by nearly all applications,
because Sun will endeavor to ensure that these continue to work in future
minor releases. Applications that depend only on Standard and Stable
interfaces should reliably continue to function correctly on future minor
releases (but not necessarily on earlier major releases).
