RE: Sort of a Data Structure Array... Idea

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

Scott, I'm not really trying to avoid QSORT.  Tony asked about Array
data-structures and SORTA.  Like everything else, one can't know why NOT to
use a particular technique unless they understand the pro's and con's of the
technique.  It is a great technique for small datasets, and works well for
some applications, but it's not really very efficient and can carry some
significant penalties.

All of this just to avoid using qsort()?  Qsort isn't just more flexible,
it's also more more efficient.

What's the drawback to using qsort() that everyone's trying to avoid it?
