Palm OS claims to provide equivalents for the normal string handling
functions, such as strncmp(), which they advise us to use. If they use
a similar naming convention for a function, such a StrNCompare(),
then they should produce an equivalent function.
If they want to create a function which acts differently, then
either; They should use a different naming scheme, such as
StrCompareLimited()
or; Explicitly document where this function differs
Can Palm Inc, comment on when StrNCompare() started requiring
null terminated strings. Has this always been the case or did it start
with OS 4.0?
