Of course AspectC++ supports pointers. Here is a revised version of your 

#include <stdio.h>

aspect abc
  pointcut res(char *d,int  g) = call("% cd(...)") && args(d, g);
  advice res(d, g) : void before (char *d,int g)
    printf ("%p-%s:%d\n", d, d, g);

void cd (char *d,int  g) {

int main () {
   cd ("my string", 42);

As you can see, there is no difference between the treatment of the 
pointer and the integer. To expose the arguments of a call, use the args 
pointcut function.



PS: we are currently working on a language reference manual, which will 
explain this with more details.
