There is at least one user of the buffer API that reuse a single buffer by just resetting `buf.len` to `0`. This works as long as the new user of the buffer actually adds something to the buffer. However, if we don't add anything but still provide `buf.buf` to a consumer, the old content will be re-used. This patch thus adds two new clearing variants to the buffer API: - `buf_clear()` which doesn't reset the internal allocations - `buf_reset()` which does free the internal allocations Additionally, this patch makes `buffer_add_char()` public which allows adding single characters to an existing buffer. This will be used in a future PR which implements custom format strings for the OSD. |
