- 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

- NAME: NLS_STR::strcspn
- SYNOPSIS: Set membership. Finds the first matching character
- in the passed string
- ENTRY: pistrPos - destination for results
- nls - set of sought characters
- EXIT: *pistrPos contains offset within "this" of element
- found (assuming it was successful); otherwise it
- is moved to the end of the string.
- RETURNS: TRUE if any character found; FALSE otherwise
