Dinkum EC++ Library

Use of this Dinkum EC++ Library Reference is subject to limitations. See the Copyright Notice for detailed restrictions.


A C++ program can call on a large number of functions from the Dinkum EC++ Library, a conforming implementation of the Embedded C++ library, as specified by the Embedded C++ Technical Committee. The Embedded C++ library is, in turn, a conforming subset of 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 Embedded C++ library can be found in the descriptions of the C++ library headers that declare or define library entities for the program.

The Embedded C++ library headers are:

<complex> -- for defining a template class that supports complex arithmetic
<exception> -- for defining several functions that control exception handling
<fstream> -- for defining several iostreams template classes that manipulate exteral files
<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
<new> -- for declaring several functions that allocate and free storage
<ostream> -- for defining the template class that performs insertions
<sstream> -- for defining several iostreams template classes that manipulate string containers
<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

The Embedded C++ library works in conjunction with 15 of the headers from the Standard C library, sometimes with small alterations. The headers come in two forms, new and traditional. The new-form headers are:

<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
<climits> -- for testing integer type properties
<clocale> -- for adapting to different cultural conventions
<cmath> -- for computing common mathematical functions
<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

The traditional Standard C library headers are:

<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
<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

Finally, in this implementation, the Embedded C++ library also includes several 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

Other information on the Embedded C++ library includes:

C++ Library Overview -- how to use the Embedded C++ library, including alternative mechanisms for handling exceptions
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
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

A few special conventions are introduced into this document specifically for this particular implementation of the Embedded C++ library. Because the C++ Standard is still relatively new, 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 C++ Standard.
