Subsecond sleep
I sometimes want to slow down animation with a small problem size and -draw_pause is generally does what I want, but it can only take integer arguments and pausing for a whole second every time is often too much. There are subsecond sleep functions (like usleep and nanosleep) in POSIX, and I've rolled my own micro-sleep command-line option more than once now. Is there a compelling reason not to make -draw_pause and PetscSleep take a real value, thus offering higher resolution when it is available? Jed -- next part -- A non-text attachment was scrubbed...

Subsecond sleep
It is fine with me to switch the infrastructure to use a PetscReal instead of integer Barry On Oct 16, 2009, at 5:02 AM, Jed Brown wrote: > I sometimes want to slow down animation with a small problem size and > -draw_pause is generally does what I want, but it can only take > integer > arguments and pausing for a whole second every time is often too much. > There are subsecond sleep functions (like usleep and nanosleep) in > POSIX, and I've rolled my own micro-sleep command-line option more > than > once now.
