This file produces the =qmckl.h= header file, which is included in all
other C header files. It is the main entry point to the library.

#+BEGIN_SRC C :tangle qmckl.h
#ifndef QMCKL_H
#define QMCKL_H
#include <stdlib.h>
#include <stdint.h>
#+END_SRC

* Constants

** Success/failure

   These are the codes returned by the functions to indicate success
   or failure. All such functions should have as a return type =qmckl_exit_code=.

    #+BEGIN_SRC C :tangle qmckl.h
#define QMCKL_SUCCESS 0
#define QMCKL_FAILURE 1

typedef int32_t qmckl_exit_code;
typedef int64_t qmckl_context ;

    #+END_SRC


** Precision-related constants

   Controlling numerical precision enables optimizations. Here, the
   default parameters determining the target numerical precision and
   range are defined.

    #+BEGIN_SRC C :tangle qmckl.h
#define QMCKL_DEFAULT_PRECISION 53
#define QMCKL_DEFAULT_RANGE     11
    #+END_SRC

* Header files

  All the functions expoed in the API are defined in the following
  header files.

   #+BEGIN_SRC C :tangle qmckl.h

#include "qmckl_memory.h"
#include "qmckl_context.h"

#include "qmckl_distance.h"
#include "qmckl_ao.h"
   #+END_SRC

* End of header

#+BEGIN_SRC C :tangle qmckl.h
#endif
#+END_SRC
