Bint,

Another more flexible method would be to snprintf() your larger string
into a temporary string buffer and then output the temporary buffer
using a standard unformatted printf(). This will allow you to
dynamically change the size of your output string by supplying a
variable length for your temporary string buffer in the snprintf()
routine (which cannot be accomplished using the "%.20s" method
described by Richard.
