Pane.exit_status

What the pane's process exited with, once it has.

Source and package

Qualified name: libtmux::Pane::exit_status
Namespace: libtmux
Declared in: Pane
Package: libtmux-cxx
Source: include/libtmux/entities.hpp

[[C++ nodiscard attributeAsks the compiler to warn when a result is discarded. An explicit cast to void acknowledges that the result is intentionally ignored.Language documentation]] std::optional<int> exit_status() const noexcept; method readonly [source] ¶: Description#

Optional rather than a number because zero is a real exit status and "still running" is not a status at all — tmux renders the field empty until the process is gone. Only a pane held on screen by remain-on-exit can report one: without it tmux destroys the pane, and there is nothing left to ask.
