NLS/DBCS-aware string class: strcmp method and equality operator
|
||
|
|
|
||
|
|
This file contains the implementation of the strcmp 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::strcmp

SYNOPSIS: Standard string compare with optional character indexes
|
||
|
|
|
||
|
|
ENTRY: nls - string against which to compare
|
||
|
|
istrStart1 (optional) - index into "this"
|
||
|
|
istrStart2 (optional) - index into "nls"
|
||
|
|
|
||
|
|
RETURNS: As the C runtime "strcmp".
|
||
|
|
|
||
|
|
NOTES: If either string is erroneous, return "match."
|
||
|
|
This runs contrary to the eqop.
|
||
|
|
|
||
|
|
Glock doesn't allow default parameters which require
|
||
|
|
construction; hence this member is overloaded multiply.
