I'd like to be able to use SysBinarySearch to search strings which
are stored as an array of pointers to a set of variable-length
strings to minimize storage space.
-- The width parameter is defined in the docs as "width of an element
comparison function". What the heck does that mean? I suspect it's
supposed to mean the width of an element, implying that
SysBinarySearch only works correctly with fixed length elements.
-- Is this true, or can you use SysBinarySearch to search a set of
variable-length strings by, perhaps, defining the width as the width
of a pointer so it knows how to move thru the array, and you deal
with the variable-length aspect in your comparison function.
Any info from anyone who's used this routine would be welcome. It
seems that none of the 3.5 sample code has any uses of
SysBinarySearch, and there's nothing in the Knowledge base other than
what's in the docs. Thanks.
Regards,
Steve Mann
