Linker Thread-Safe Features

Beginning with the HP-UX 10.30 release, the dynamic loader (dld.sl) and its application interface library (libdld.sl) are thread-safe.

Also, beginning with the HP-UX 10.30 release, the linker toolset provides thread local storage support in:

Thread local storage (also called thread-specific data) is data specific to a thread. Each thread has its own copy of the data item.




	NOTE: A program with thread local storage is only supported on systems running HP-UX 10.30 or later versions of the operating system.Use of the `__thread` keyword in a shared library prevents that shared library from being dynamically loaded, that is, loaded by an explicit call to `shl_load()`.

See your HP compiler documentation to learn how to create thread local storage data items with the _thread compiler directive.
See Programming with Threads on HP-UX for information on threads.
