Function returning pointer to itself?

Question

Is it possible in C++ to write a function that returns a pointer to itself?

If no, suggest some other solution to make the following syntax work:

som         


        

Answer 1

Of course it is possible, just look the following code:

#include 

typedef void * (*func)();

void * test()
{
    printf("this is test\n");
    return (void *)&test;
}

int main()
{
    (*(func)test())();
}

The result is :

user@linux:~/work/test> gcc test_func.cc -o test          
user@linux:~/work/test> ./test
this is test
this is test
