Yep, strncpy may not NUL terminate, so using it is awkward as detailed here: http://www.pixelbeat.org/programming/gcc/string_buffers.html stpcpy/stpncpy are appropriate here as the buffer is just the right size, so you don't waste cycles filling with NULs etc. Often it's simpler/faster to fall back to memcpy for C string buffers as I did in buffer_or_output() here: http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=b1428e31 patch looks good. cheers, Pádraig.
