/* Here is a macro that will define typemaps for converting between C
   arrays and Scheme lists or vectors when passing arguments to the C
   function.

   TYPEMAP_LIST_VECTOR_INPUT_OUTPUT(C_TYPE, SCM_TO_C, C_TO_SCM, SCM_TYPE)
   
   Supported calling conventions:

   func(int VECTORLENINPUT, [const] C_TYPE *VECTORINPUT)

       Scheme wrapper will take one argument, a vector.  A temporary C
       array of elements of type C_TYPE will be allocated and filled
       with the elements of the vectors, converted to C with the
       SCM_TO_C function.  Length and address of the array are passed
       to the C function.

       SCM_TYPE is used to describe the Scheme type of the elements in
       the Guile procedure documentation.
   
   func(int LISTLENINPUT, [const] C_TYPE *LISTINPUT)

       Likewise, but the Scheme wrapper will take one argument, a list.

   func(int *VECTORLENOUTPUT, C_TYPE **VECTOROUTPUT)

       Scheme wrapper will take no arguments.  Addresses of an integer
       and a C_TYPE * variable will be passed to the C function.  The
       C function is expected to return address and length of a
       freshly allocated array of elements of type C_TYPE through
       these pointers.  The elements of this array are converted to
       Scheme with the C_TO_SCM function and returned as a Scheme
       vector. 

       If the function has a void return value, the vector constructed
       by this typemap becomes the return value of the Scheme wrapper.
       Otherwise, the function returns multiple values.  (See
       the documentation on how to deal with multiple values.)

   func(int *LISTLENOUTPUT, C_TYPE **LISTOUTPUT)

       Likewise, but the Scheme wrapper will return a list instead of
       a vector.

   It is also allowed to use "size_t LISTLENINPUT" rather than "int
   LISTLENINPUT".  */
