Hi, folks,

i'm studing how to call C functions from Clean. I already know htoclean and i had some problems to understand how the example "example_array1" works. Being more specific why the index [-2] and [-1] in the following code?

#define CleanIntArraySize(clean_int_array) (((unsigned int *)(clean_int_array))[-2])

#define CleanRealArraySize(clean_real_array) (((unsigned int *)(clean_real_array))[-2])

#define CleanCharArraySize(clean_char_array) (((unsigned int *)(clean_char_array))[-1])

There is a new version of htoclean? 
Anybody is studing how to call C function from Clean too?

Thanks in advance,

Hugo Leonardo
