NLS/DBCS-aware string class: strtok method
This file contains the implementation of the strtok method
for the STRING class. It is separate so that clients of STRING which
do not use this operator need not link to it.

NAME: NLS_STR::strtok
SYNOPSIS: Basic strtok functionality. Returns FALSE after the
string has been traversed.
ENTRY:
EXIT:
NOTES: We don't update the version on the string since the
::strtokf shouldn't cause DBCS problems. It would also
be painful on the programmer if on each call to strtok
they had to update all of the ISTR associated with this
string
fFirst is required to be TRUE on the first call to
strtok, it is FALSE afterwards (is defaulted to FALSE)
CAVEAT: Under windows, all calls to strtok must be done while
processing a single message. Otherwise another process
my confuse it.
