[Qemu-devel] [RFC 08/15] error: New ERR_IS_* macros for checking Error** values |
Date: |
Tue, 13 Jun 2017 13:53:06 -0300 |
Define new macros that should be used when checking errp values.
Existing methods will still work by now, but will break once we
implement IGNORE_ERRORS in a different way later. Other patches will
convert existing code to use the new macros.
TODO: write more detailed API documentation
