Solaris 2.5, x86, cancelation of cond_wait will not unlock mutex

Solaris 2.5, x86, cancelation of cond_wait will not unlock mutex

Post by Arne Varho » Sat, 07 Oct 1995 04:00:00

I have started working with the Posix threads in 2.5 EA aug 95, the
cond_wait() function is a implicit cancelation point, but it will not
unlock the mutex if it is canceled. So I must set up a cancelation routine
only to unlock the mutex.
I can't find any reason for not unlocking the mutex at cancelation since
the thread is stopped and the mutex can't be unlocked by another thread.

Is this a bug, or is there a reason ?

1. FS: Solaris 2.5 Desktop (CDE) and/or Solaris 2.5 Server Packages for x86 desktops

 Hi All,

  Just wanted to pass on some excellent deals on Solaris 2.5.1 software with
the WABI user interface for x86 machines. The WABI allows you to run many
Windows 3.1 applications on a UNIX box, giving you the best of both worlds.  
Imagine, running MS OFFICE components like, MS Word for Windows, Excel,
Powerpoint, and interfacing with the functionality of UNIX at the same time.

For a limited time, John Cristy, at Executive Tools, Inc.,
is offering:

  Solaris 2.5.1 User Desktop package for $175.00
  Solaris 2.5.1 Application Server package for $395.00

Ref URL for full information and additional products.  

They also have a student special (99.00 + shipping)(yes, you read that
right, Solaris 2.5.1 user desktop for $99.00).

Mention my name, Bob Fahey, and he will throw in the Java Workshop for
$85.00. Mention my name anyway, as he wants to know what the response is to
If asked where you heard this, tell them not just the web, but the Newsgroup
you read it on.  Thanks.

The Executive Tools web site URL also has some
excellent links to other Solaris and Sun information pages.
