I call remove (p,ec); and get a compile-time error that no form takes two arguments. Looking in the header, that seems to be the case. The Filesystem Reference (http://www.boost.org/doc/libs/1_43_0/libs/filesystem/doc/reference.html) clearly shows an error code parameter. I understand this module is tracking the standardization process. So which is newer? Should I be anticipating the code change to match the docs, or vice versa? How do I find out if there was an error and report the details? Note that I want to consider the case of the file not existing in the first place as OK. --John TradeStation Group, Inc. is a publicly-traded holding company (NASDAQ GS: TRAD) of three operating subsidiaries, TradeStation Securities, Inc.
