ISO/IEC 9,899:2011 introduction

Introduction

1. With the introduction of new devices and extended character sets, new features may be added to this international standard. The sub-clause in this language and library clause reminds the user of the usage that the creator and the programmer may have in conflict with the new features in the future, although they are now legally valid.

2. Some features are progressively discarded, which means that these features may be considered for removal from this international standard in future revisions. They are now reserved because they are still being used extensively, but they are not encouraged in the new implementation (for implementation features) or new programs (for language [6.11] or library attributes [7.31]).
