When using the use function on autoClosable classes that implement close(). Is there a way I can get the suppressed exceptions to log them?

[mkrussel]

The Kotlin Exception class is a type alias to the Java one if you are on JVM. You can then use the getSuppressed function on Throwable to see anything that was suppressed.

so I wrap the use with getSupressed()?

[mkrussel]

No you have to catch the exception (try/catch) and then look at what exception was suppressed (if any) by that exception.

[mkrussel]

use will throw any exception thrown by your block or by the close function of the Closable.

If they both throw exceptions, then the one thrown by your code block, will have the one from the close added to it as a suppressed exception.

[mkrussel]

The suppress is a way to report that two exceptions were thrown since only one can actually get thrown by a function.
