strlcat provides better protection against buffer overflows. Code is taken from the FreeBSD project source code. Specifically: https://github.com/freebsd/freebsd/blob/master/lib/libc/string/strlcat.c License appears to be acceptable, but needs to be checked by e.g. Debian. Step 1: 1. Add to netcdf-c/include/ncconfigure.h to use our version if not already available as determined by HAVE_STRLCAT in config.h. 2. Add the strlcat code to libdispatch/dstring.c 3. Turns out that strlcat was already defined in several places. So remove it from: ncgen3/genlib.c ncdump/dumplib.c 3. Define strlcat extern definition in ncconfigure.h. 4. Modify following directories to use strlcat: libdap2 libdap4 ncdap_test dap4_test Will do others in subsequent steps.
