Dear R users,
I am trying to include C code into R via the .C interface. I have read
that arguments passed to a C function have to be correctly DEreferenced.
This is something that can be easily done for numbers (integers or
float) by adding
a * before the reference like for instance:
------------------------------------------------------------------------
#include<R.h>
void hellofct(int *n)
{
int i;
for (i=0;i<*n;i++)
{
Rprintf("Hello, world!\n");
}
}
------------------------------------------------------------------------
However, I can not figure out how that can be achieved for strings.
My prototype function would be something like:
------------------------------------------------------------------------
#include<R.h>
void displaystring(char *str)
{
Rprintf("String displayed:%s\n", ????);
}
------------------------------------------------------------------------
any hints?
Thx.
Stéphane.
