1 Headers

To use the facilities of C conveniently we first define some classes naming the standard header files.

The class construction provides a namespace.

The contained header specification provides a tag name for a C include line. A use of a type or function lifted from C depending on the inclusion of the header text causes the Felix compiler to emit the header text.

2 C Standards.

Each newer C Standard adds some header files. The inherit statement is used to include the headers from the previous standard into a more recent one.

2.1 C89 Standard.

The original ANSI Standard blessed as an ISO Standard.

id=line1> // reference: Wikipedia: http://en.wikibooks.org/wiki/C_Programming/Reference_Tables#List_of_Standard_Headers // ANSI C89 = ISO C90 class C89_headers { header assert_h = "#include <assert.h>"; header ctype_h = "#include <ctype.h>"; header errno_h = "#include <errno.h>"; header float_h = "#include <float.h>"; header limits_h = "#include <limits.h>"; header locale_h = "#include <locale.h>"; header math_h = "#include <math.h>"; header setjmp_h = "#include <setjmp.h>"; header signal_h = "#include <signal.h>"; header stdarg_h = "#include <stdarg.h>"; header stddef_h = "#include <stddef.h>"; header stdio_h = "#include <stdio.h>"; header stdlib_h = "#include <stdlib.h>"; header string_h = "#include <string.h>"; header time_h = "#include <time.h>"; }

2.2 C95 Amendment

Added support for wide characters.

share/lib/std/c/c_headers.flx

  // ISO C94/95 Amendment 1
  class C95_headers  
  {
    inherit C89_headers;
    header iso646_h =   "#include <iso646.h>";
    header wchar_h =    "#include <wchar.h>";
    header wctype_h =   "#include <wctype.h>";
  }

2.3 C99 Standard

Added support for complex, exact integer types and bool.

share/lib/std/c/c_headers.flx

  // ISO C99
  class C99_headers 
  {
    inherit C95_headers;
    header complex_h =  "#include <complex.h>";
    header fenv_h =     "#include <fenv.h>";
    header inttypes_h = "#include <inttypes.h>";
    header wctype_h =   "#include <wctype.h>";
    header stdbool_h =  "#include <stdbool.h>";
    header stdint_h =   "#include <stdint.h>";
    header tgmath_h =   "#include <tgmath.h>";
  }

3 C++ Standards.

Each newer C++ Standard adds some header files. The inherit statement is used to include the headers from the previous standard into a more recent one.

3.1 C++90 Standard

The original C++ Standard.

5 Windows
