octave datatypes and c datatypes Is there a 1 a 1 relationship between arrays?

[Riccardo Corradini]

Hi all,
I would like to know if there is one to one relationship between octave datatypes and C data types
For istance I defined the following macro 
#define UPACK_INT_ARRAY(CASE,FTYPE,PRMTYP, PTRTYP)    \
/*---------------------------------------*/                \
int unpack_##CASE##_mat(const PRMTYP &array){                \
/*---------------------------------------*/                \
  int n  = array.nelem();                        \
  int info;                                \
  const PTRTYP *pointer  =
 reinterpret_cast<const PTRTYP *>(array.fortran_vec());            \
  if((info=FTYPE(pointer,n,1))) return(info);    \
  return(PvmOk);                            \
}

  UPACK_INT_ARRAY(i8 ,pvm_upkbyte, int8NDArray ,          char)
  UPACK_INT_ARRAY(i16,pvm_upkshort ,int16NDArray,          short)
  UPACK_INT_ARRAY(i32,pvm_upkint ,int32NDArray,          int)

  UPACK_INT_ARRAY(u8 ,pvm_upkbyte ,uint8NDArray , char)
  UPACK_INT_ARRAY(u16,pvm_upkushort ,uint16NDArray, unsigned short)
  UPACK_INT_ARRAY(u32,pvm_upkuint ,uint32NDArray, unsigned int)


I am sure that even if it might work it is not
 the right procedure suggested in general by JWE,so what is the best strategy to convert an int .. array into a c array and viceversa. Is it possible to avoid reinterpret cast etc.. 
Thanks in advance to all
Riccardo
