Dinkum C++ Library Reference

 


A C++ program can call on a large number of functions from the Standard C++ library. These functions perform essential services such as input and output. They also provide efficient implementations of frequently used operations. Numerous function and class definitions accompany these functions to help you to make better use of the library. Most of the information about the Standard C++ library can be found in the descriptions of the Standard C++ headers that declare or define library entities for the program.

Of the 51 Standard C++ library headers, 13 constitute the Standard Template Library, or STL. These are indicated below with the notation (STL):

<algorithm> -- (STL) for defining numerous templates that implement useful algorithms
<bitset> -- for defining a template class that administers sets of bits
<cassert> -- for enforcing assertions when functions execute
<cctype> -- for classifying characters
<cerrno> -- for testing error codes reported by library functions
<cfloat> -- for testing floating-point type properties
<ciso646> -- for programming in ISO 646 variant character sets
<climits> -- for testing integer type properties
<clocale> -- for adapting to different cultural conventions
<cmath> -- for computing common mathematical functions
<complex> -- for defining a template class that supports complex arithmetic
<csetjmp> -- for executing nonlocal goto statements
<csignal> -- for controlling various exceptional conditions
<cstdarg> -- for accessing a varying number of arguments
<cstddef> -- for defining several useful types and macros
<cstdio> -- for performing input and output
<cstdlib> -- for performing a variety of operations
<cstring> -- for manipulating several kinds of strings
<ctime> -- for converting between various time and date formats
<cwchar> -- for manipulating wide streams and several kinds of strings
<cwctype> -- for classifying wide characters
<deque> -- (STL) for defining a template class that implements a deque container
<exception> -- for defining several functions that control exception handling
<fstream> -- for defining several iostreams template classes that manipulate exteral files
<functional> -- (STL) for defining several templates that help construct predicates for the templates defined in <algorithm> and <numeric>
<iomanip> -- for declaring several iostreams manipulators that take an argument
<ios> -- for defining the template class that serves as the base for many iostreams classes
<iosfwd> -- for declaring several iostreams template classes before they are necessarily defined
<iostream> -- for declaring the iostreams objects that manipulate the standard streams
<istream> -- for defining the template class that performs extractions
<iterator> -- (STL) for defining several templates that help define and manipulate iterators
<limits> -- for testing numeric type properties
<list> -- (STL) for defining a template class that implements a list container
<locale> -- for defining several classes and templates that control locale-specific behavior, as in the iostreams classes
<map> -- (STL) for defining template classes that implement associative containers
<memory> -- (STL) for defining several templates that allocate and free storage for various container classes
<new> -- for declaring several functions that allocate and free storage
<numeric> -- (STL) for defining several templates that implement useful numeric functions
<ostream> -- for defining the template class that performs insertions
<queue> -- (STL) for defining a template class that implements a queue container
<set> -- (STL) for defining template classes that implement associative containers with unique elements
<sstream> -- for defining several iostreams template classes that manipulate string containers
<stack> -- (STL) for defining a template class that implements a stack container
<stdexcept> -- for defining several classes useful for reporting exceptions
<streambuf> -- for defining template classes that buffer iostreams operations
<string> -- for defining a template class that implements a string container
<strstream> -- for defining several iostreams classes that manipulate in-memory character sequences
<typeinfo> -- for defining class type_info, the result of the typeid operator
<utility> -- (STL) for defining several templates of general utility
<valarray> -- for defining several classes and template classes that support value-oriented arrays
<vector> -- (STL) for defining a template class that implements a vector container

The Standard C++ library also includes the 18 headers from the Standard C library, sometimes with small alterations:

<assert.h> -- for enforcing assertions when functions execute
<ctype.h> -- for classifying characters
<errno.h> -- for testing error codes reported by library functions
<float.h> -- for testing floating-point type properties
<iso646.h> -- for programming in ISO 646 variant character sets
<limits.h> -- for testing integer type properties
<locale.h> -- for adapting to different cultural conventions
<math.h> -- for computing common mathematical functions
<setjmp.h> -- for executing nonlocal goto statements
<signal.h> -- for controlling various exceptional conditions
<stdarg.h> -- for accessing a varying number of arguments
<stddef.h> -- for defining several useful types and macros
<stdio.h> -- for performing input and output
<stdlib.h> -- for performing a variety of operations
<string.h> -- for manipulating several kinds of strings
<time.h> -- for converting between various time and date formats
<wchar.h> -- for manipulating wide streams and several kinds of strings
<wctype.h> -- for classifying wide characters

Finally, in this implementation, the Standard C++ library also includes four headers for compatibility with traditional C++ libraries:

<fstream.h> -- for defining several iostreams template classes that manipulate exteral files
<iomanip.h> -- for declaring several iostreams manipulators that take an argument
<iostream.h> -- for declaring the iostreams objects that manipulate the standard streams
<new.h> -- for declaring several functions that allocate and free storage
<stl.h> -- for declaring several template classes that aid migration from older versions of the Standard Template Library

Other information on the Standard C++ library includes:

C++ Library Overview -- how to use the Standard C++ library
C Library Overview -- how to use the Standard C library, including what happens at program startup and at program termination
Characters -- how to write character constants and string literals, and how to convert between multibyte characters and wide characters
Files and Streams -- how to read and write data between the program and files
Formatted Output -- how to generate text under control of a format string
Formatted Input -- how to scan and parse text under control of a format string
STL Conventions -- how to read the descriptions of STL template classes and functions
Containers -- how to use an arbitrary STL container template class

A few special conventions are introduced into this document specifically for this particular implementation of the Standard C++ library. Because the draft C++ Standard is still changing, not all implementations support all the features described here. Hence, this implementation introduces macros, or alternative declarations, where necessary to provide reasonable substitutes for the capabilities required by the current draft C++ Standard.
