|
|
*** THIS IS AN ALTERED VERSION. It was altered by Benoit
|
||
|
|
*** Goudreault-Emond, bge@videotron.ca, on 2002/01/03, to add \< and
|
||
|
|
*** \> for word matching, as well as pseudo character classes. It
|
||
|
|
*** also handles wide characters quite well now. Also, the API was
|
||
|
|
*** changed so an arbitrary number of parenthesized expressions can
|
||
|
|
*** be used (and so were the internals of the regexp engine).
|
||
|
|
***
|
||
|
|
*** In general, the new API should be more re-entrant.
