Networking services
New X/Open standardized socket and IP address resolution interfaces are
available.
The X/Open Transport Interface (XTI) is an evolution and standardization of
the set of interfaces that were supported by the Transport Layer Interface (TLI)
in SVR4. TLI continues to be available for compatibility, but new development
should use XTI.
For more information, see Transport Interfaces Programming Guide.
X/Open XFN CAE
Federated Naming Service (FNS) is now compliant with the X/Open XFN CAE
definition.
POSIX 1003.1b
POSIX 1003.1b support is completed. The Solaris software has provided all of the
interfaces for POSIX 1003.1b since the Solaris 2.3 release. A subset of those interfaces
was functional in that they provided services instead of returning “Not Supported.”
This release finishes support for POSIX 1003.1b (with the exception of the
PRIORITIZED IO option).
This standards feature is of interest to developers interested in writing portable,
standards-compliant code. It is also of interest to developers interested in higher
performance message passing or semaphore code who otherwise would use System
V messages or semaphores and who can accept the more limited functionality
offered by POSIX.
As of the Solaris 2.6 release, POSIX 1003.1b support is provided for the following:
Asynchronous I/O (except prioritized I/O)
Mapped files
Memory locking
Memory protection
Message passing
Priority scheduling
Realtime signals
Semaphores
File synchronization
Shared memory objects
