```haskell
tryTmux
  :: IO a
  -> IO (Either (ExceptionWithContext TmuxException) a)
```

Signature types: [`IO`](https://hackage.haskell.org/package/base-4.22.0.0/docs/Prelude.html#t:IO), [`Either`](https://hackage.haskell.org/package/base-4.22.0.0/docs/Data-Either.html#t:Either), [`ExceptionWithContext`](https://hackage.haskell.org/package/base-4.22.0.0/docs/Control-Exception.html#t:ExceptionWithContext), [`TmuxException`](/en/haskell/latest/reference/libtmux-server-t-tmuxexception/).

Catch library failures with their exception context. Retain this value
 when handling an error so cleanup and capture owners stay reachable.
 Application exceptions and asynchronous cancellation propagate.
