Appendix A: Standard Library Headers

The C++ Standard Library consists of 79 header files, of which 26 are adapted from the C Standard Library. This appendix gives a brief description of each.
For each < name .h> header from the C Standard Library, there is a corresponding <c name > C++ Standard Library header (note the c prefix). These C++ headers put all functionality provided by the C library in the std namespace. It is implementation-defined whether the types and functions still appear in the global namespace. The use of the original <name.h> headers is deprecated.
Headers are shown in the order in which they are presented in each chapter. Functionality not discussed in this book is shown in italic.
