Construct a list expression. The list's nodes' data should
themselves be {\bf wxExpr}s.

list.
error handler must be a function returning a bool and taking an integer and a string
argument. When an error occurs when reading or writing a database, this function is
called. The error is given as the first argument (currently one of WXEXPR\_ERROR\_GENERAL,
-WXEXPR\_ERROR\_SYNTAX) and an error message is given as the second argument. If FALSE
+WXEXPR\_ERROR\_SYNTAX) and an error message is given as the second argument. If false
is returned by the error handler, processing of the wxExpr operation stops.
Another way of handling errors is simply to call \helpref{wxExprDatabase::GetErrorCount}{wxexprdatabasegeterrorcount} after
the operation, to check whether errors have occurred, instead of installing an error handler.
If the error count is more than zero, \helpref{wxExprDatabase::Write}{wxexprdatabasewrite} and
-\rtfsp\helpref{wxExprDatabase::Read}{wxexprdatabaseread} will return FALSE to
+\rtfsp\helpref{wxExprDatabase::Read}{wxexprdatabaseread} will return false to
the application.
For example:
{
wxMessageBox(msg, "Syntax error");
}
- return FALSE;
+ return false;
}
wxExprDatabase database(myErrorHandler);
