libtmux.control:await-request

Wait for owned result/:READY, or return NIL/:TIMEOUT without cancelling. TIMEOUT is nonnegative real seconds or NIL for an unbounded wait. Zero polls. The result plist contains :STATUS, :OUTPUT bytes, :WIRE-TAIL bytes, :TRUNCATED-P, :EFFECT, :DISPATCHED-P, :REASON and :REPLY-COUNT. Wire tail is unterminated protocol data, not decoded output. Positive stdin progress makes DISPATCHED-P true conservatively, even for an incomplete line. A dispatched failed/cancelled/timed-out/closed request may have effects; never infer rollback. COMPLETED means the command queue reached its marker, not application readiness. Only framed replies enter OUTPUT; unframed lines remain notification events. Repeated awaits return fresh byte storage. No exception hides a terminal result.
