Subject: pactl: Flush stdout buffer when printing subscribe events.
X-Git-Url: https://code.delx.au/pulseaudio/commitdiff_plain/8cc4e7786f04929c55f12d480b38bb484506eee4

pactl: Flush stdout buffer when printing subscribe events.

"pactl subscribe" is running continuously, and without flushing its output is
not usable for "process-on-arrival" per-line tasks, such as grepping. This
patch should fix this. For example, now:
pactl subscribe | grep 'server'
should print only server events as they arrive.
