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.
