Change subject: libusb_util.c: Avoid gcc warning about strncpy() ...................................................................... libusb_util.c: Avoid gcc warning about strncpy() What we're doing is actually legal: We copy the full size of the destination array, and then overwrite the last byte with NUL. However, gcc isn't smart enough to see that: libusb_util.c:162:5: warning: ‘strncpy’ specified bound 20 equals destination size [-Wstringop-truncation] strncpy(out[out_idx].path, path, sizeof(out[out_idx].path)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let's copy one byte less to make it happy.
