Specify one less than sizeof the target buffer to avoid this diagnostic.
Since the target buffer is pre-zeroed, the string will be NUL-terminated.
This is a fixed-length string field that is not supposed to be
NUL-terminated. The use of strncpy() here is deliberate in order to be
able to completely fill the field.
Is there a (clean) way to indicate to gcc to ignore this false positive
warning?
Thanks,
