- NLS/DBCS-aware string class: strcspn method
- This file contains the implementation of the strcspn method
- for the STRING class. It is separate so that clients of STRING which
- do not use this operator need not link to it.
- FILE HISTORY:
- beng 01/18/91 Separated from original monolithic .cxx
- beng 02/07/91 Uses lmui.hxx
