Subject: If str == buffer, then do NOT do a strncpy(buffer, str).  Many systems
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/ba8b265a8211b2052b424dc9bd7ea391a8ded87a?ds=inline;hp=ba8b265a8211b2052b424dc9bd7ea391a8ded87a

If str == buffer, then do NOT do a strncpy(buffer, str).  Many systems
this works, but on some systems it causes a SIGABRT.  POSIX says the
behavior on overlapping copies with str*cpy() is officially undefined.
