In directory sc8-pr-cvs1:/tmp/cvs-serv22379/Doc/lib

Modified Files:
	libsignal.tex 
Log Message:
Take out my (long since disabled) POSIX signal mask handling code.

I'm not going to have the time or energy to get this working x-platform
-- anyone who does is welcome to the code!

- \begin{funcdesc}{sigprocmask}{how, sigset}
-   Change the list of currently blocked signals.  The parameter
-   \var{how} should be one of \constant{SIG_BLOCK},
-   \constant{SIG_UNBLOCK} or \constant{SIG_SETMASK} and \var{sigset}
-   should be a sequence of signal numbers.  The behaviour of the call
-   depends on the value of \var{how}:

-            {The signals in \var{sigset} are removed from the current

-     \lineii{\constant{SIG_SETMASK}}
- 	   {The set of blocked signals is set to the \var{sigset}.}

-   A list contating the numbers of the previously blocked signals is
-   returned.

- 
- \begin{funcdesc}{sigsuspend}{sigset}
-   Temporarily replace the signal mask with \var{sigset} (which should
-   be a sequnce of signal numbers) and suspend the process until a
