Last change on this file since 7f6a24ab was 7f6a24ab, checked in by Joel Sherrill <joel.sherrill@…>, on Aug 28, 1995 at 3:30:29 PM

Added unused priority ceiling parameter to rtems_semaphore_create.

Rearranged code to created thread handler routines to initialize,
start, restart, and "close/delete" a thread.

Made internal threads their own object class. This now uses the
thread support routines for starting and initializing a thread.

Insured deleted tasks are freed to the Inactive pool associated with the
correct Information block.

Added an RTEMS API specific data area to the thread control block.

Beginnings of removing the word "rtems" from the core.
