<DL COMPACT>
<DT> 
<DD> 
sets <EM>value</EM> and <EM>interval</EM> in <EM>timer</EM>.
<EM>timer</EM> is eiterh  0 (<TT>ITIMER_REAL</TT>), 1 (<TT>ITIMER_VIRTUAL</TT>),
or 2(<TT>ITIMER_PROF</TT>).
<TT>ITIMER_REAL</TT> delivers SIGALRM when <EM>value</EM> expires.
<TT>ITIMER_VIRTUAL</TT> delivers SIGVTALRM, and 
<TT>ITIMER_PROF</TT> delivers SIGPROF.
