Boost-Commit : |
From: bdawes_at_[hidden]
Date: 2007-08-21 14:11:33
Author: bemandawes
Date: 2007-08-21 14:11:33 EDT (Tue, 21 Aug 2007)
New Revision: 38833
URL: http://svn.boost.org/trac/boost/changeset/38833
Log:
Add separate error_condition class, with enable_if to distinguish overloads. Add make_error_code for posix, to allow explicit use of posix enums as portable error_codes in addition to implicit conversion to error_condition.
