Time waits for ca-pend-event on Solaris/SPARC

[Gary P Carr <gcarr@lanl.gov>]

Does anyone know what the actual timeouts will be for a ca_pend_event(timo) 
call on a Solaris/SPARC machine? I guess the real question is does SPARC 
normally have a "real" realtime clock, or does it use a line clock with 
60Hz tics?

If I call ca_pend_event(0.0001), does it block for at least:

1) 0.0001 seconds
2) until the next tic
3) at least one tic (0.01667 seconds)
