/* ------------------------------------------------------------
 * Primitive type fragments and macros 
 * ------------------------------------------------------------ */

/*
  This file provide fragments and macros for the C/C++ primitive types. 

  The file defines default fragments for the  following types:

    bool
    signed char
    unsigned char
    signed wchar_t     // in C++
    unsigned wchar_t   // in C++
    short
    unsigned short
    int
    unsigned int
    float

  which can always be redefined in the swig target languge if needed.
  
  The fragments for the following types, however, need to be defined
  in the target language always:

    long
    unsigned long
    long long
    unsigned long long
    double
 
  If they are not provided, an #error directive will appear in the
  wrapped code.

  --------------------------------------------------------------------
  
  This file provides the macro

    %typemaps_primitive(CheckCode, Type)

  which generate the typemaps for a primitive type with a given
  checkcode. It is assumed the the primitive type is 'normalized' and
  the corresponding SWIG_AsVal(Type) and SWIG_From(Type) methods are
  provided via fragments.
  
   
  The following auxiliar macros (explained with bash pseudo code) are
  also defined:

    %apply_ctypes(Macro)        
      for i in C Type 
      do
        Macro($i)
      done

    %apply_cpptypes(Macro) 
      for i in C++ Type 
      do
        Macro($i)
      done

    %apply_ctypes_2(Macro2)     			     
       for i in C Type 					     
       do							     
         for j in C Type 					     
         do						     
            Macro_2($i, $j)				     
         done						     
       done						     
    							     
    %apply_cpptypes_2(Macro2)     			     
       for i in C++ Type 					     
       do							     
         for j in C++ Type 				     
         do						     
            Macro_2($i, $j)				     
         done						     
       done						     
    							     
    %apply_checkctypes(Macro2)
       for i in Check Type 
       do
         Macro2(%checkcode($i), $i)
       done
