- * @function backtrace_async
- * Extracts the function return addresses of the current call stack. While
- * backtrace() will only follow the OS call stack, backtrace_async() will
- * prefer the unwind the Swift concurrency continuation stack if invoked
- * from within an async context. In a non-async context this function is
- * strictly equivalent to backtrace().
- *
- * @param array
- * The array of pointers to fill with the return addresses.
- *
- * @param length
- * The maximum number of pointers to write.
- *
- * @param task_id
- * Can be NULL. If non-NULL, the uint32_t pointed to by `task_id` is set to
- * a non-zero value that for the current process uniquely identifies the async
- * task currently running. If called from a non-async context, the value is
- * set to 0 and `array` contains the same values backtrace() would return.
- *
- * Note that the continuation addresses provided by backtrace_async()
- * have an offset of 1 added to them.  Most symbolication engines will
- * substract 1 from the call stack return addresses in order to symbolicate
- * the call site rather than the return location.  With a Swift async
- * continuation, substracting 1 from its address would result in an address
- * in a different function.  This offset allows the returned addresses to be
- * handled correctly by most existing symbolication engines.
- *
- * @result
- * The number of pointers actually written.
