What's this mbetutils test of snprintf() about? Found while searching for Zephyr use of snprintf() function in ~/projects/zephyr-based/z4-sandbox-kionix-work/zephyr:
./tests/crypto/mbedtls/src/mbedtls.c:65:#define mbedtls_snprintf snprintf
./tests/crypto/mbedtls/src/mbedtls.c:89:static int test_snprintf(size_t n, const char ref_buf[10], int ref_ret)
./tests/crypto/mbedtls/src/mbedtls.c:95: ret = mbedtls_snprintf(buf, n, "%s", "123");
./tests/crypto/mbedtls/src/mbedtls.c:108:static int run_test_snprintf(void)
