The type is just a wrapper around a c_int and is used as the type of the error codes that are still declared in SysBasic. Its naming convention comes from our runtime support of IO and feels very much like an implementation detail.
In a meeting discussing the SysBasic module, it sounded like the lean was to use c_int instead and if we did keep qio_err_t in some form, make it an internal type, renaming it to start with chpl_.
