My understanding of
http://www.boost.org/doc/libs/1_40_0/libs/system/doc/reference.html#Non-
member-functions is that error_category.equivalent() is there to
abstract this. operator== is overloaded on error_code and
error_condition to perform that equivalence check, so this should do
what you want:
catch (const basic_filesystem_error& e){
if (e == make_error_condition(posix_error::no_space_on_device)){
//...
}
}
