Subject: ffs.3: All these functions live in <strings.h>.
X-Git-Tag: man-pages-6.06~137

ffs.3: All these functions live in <strings.h>.

In most cases you'll get them transitively through <string.h>, but it's
misleading for the man page to claim that they're _in_ <string.h>, and
especially weird to claim they're in _different_ headers from each
other!

This is also true of Apple's headers, and FreeBSD (the other BSDs only
have ffs(), not its siblings).
