Well, I think it should work for an integer too, but in the language 
reference the login function is not listed, so it may be different of my 
one, that is defined only as : void nop(...){};

But something strange is happening in my test program. I have tried your 
suggestion and got a segmentation fault.  My latest unsuccessful try was:

#include <stdio.h>

void nop(const char *){};

void nop(int){};

class MyClass {

   int doit ( int aa ) {
     int bb;

     bb = aa * 5;


     char myName[10] = "here";


     return (bb + 2);

int main() {

  MyClass mine;



aspect myAspect {

   pointcut log1 (int zz) = args(zz) && call ("void nop(...)");
   pointcut log2 (const char * name) = args(name) && call ("void nop(...)");

   advice log1 (zz) : before(int zz)  {

      printf("The local value is %d \n", zz);


   advice log2 (name) : before(const char * name)  {
      printf("The local string is %s \n", name);

It works only if I remove the log2 advice.

That code is different of what I have planned as I wanted the nop funcion be 
declared as "void nop(...)", and so I would declared it only once in the
