Re: Passing arrays to C funcions

Hi all,

I have to pass an array of doubles to a legacy C function that copies
some data using memcpy. The code would look like this:

extern "C"{
void legacyCFunctionFill(void* arg);
}
...
int number=5;
double *my_array=(double*)calloc(number,sizeof(double));
legacyCFunctionFill((void*)my_array);
// Do sth useful
free(my_array);

The question is: if I change calloc() and free() with new and delete
[] will there be any issues, including portability issues? At first it
seems that it works, having tested that in my program. But I am not
sure if the memory allocated by calloc is the same and can be used the
same way as the memory allocated with new, especially on windows,
Linux and Sun.
