I don't see an strndup() function in our libc. keramida@kobe:/usr/src/lib/libc/string$ grep ^strdup *.c strdup.c:strdup(str) keramida@kobe:/usr/src/lib/libc/string$ grep ^strndup *.c keramida@kobe:/usr/src/lib/libc/string$ While it seems like a cool function name, what's the point of having it? If you know how much you want to copy, it's trivial to allocate a buffer large enough and strlcpy() into it. If you don't know how much you want to copy, then strdup() is ok anyway :)
