- * The tools so far have been using the strerror_r() GNU variant, that returns
- * a string, be it the buffer passed or something else.
- *
- * But that, besides being tricky in cases where we expect that the function
- * using strerror_r() returns the error formatted in a provided buffer (we have
- * to check if it returned something else and copy that instead), breaks the
- * build on systems not using glibc, like Alpine Linux, where musl libc is
- * used.
- *
- * So, introduce yet another wrapper, str_error_r(), that has the GNU
- * interface, but uses the portable XSI variant of strerror_r(), so that users
- * rest asured that the provided buffer is used and it is what is returned.
