適用范圍：1 This Technical Report describes extensions to the C++ standard library that is described in the InternationalStandard for the C++ programming language [14].2 This Technical Report is non-normative. Some of the library components in this Technical Report may be consideredfor standardization in a future version of C++, but they are not currently part of any C++ standard. Some of thecomponents in this Technical Report may never be standardized, and others may be standardized in a substantiallychanged form.3 The goal of this Technical Report is to build more widespread existing practice for an expanded C++ standardlibrary. It gives advice on extensions to those vendors who wish to provide them.1.1 Relation to C++ Standard Library Introduction [tr.description]1 Unless otherwise specified, the whole of the ISO C++ Standard Library introduction [lib.library] is included in thisTechnical Report by reference.1.2 Categories of extensions [tr.intro.ext]1 This Technical Report describes four general categories of library extensions:1. New requirement tables, such as the regular expression traits requirements in 7.2. These are not directlyexpressed as software; they specify the circumstances under which user-written components will interoperatewith the components described in this Technical Report.2. New library components (types and functions) that are declared in entirely new headers, such as the classtemplates in the
