((int (*)(char *)) p)("hello, world");
The secret here is the parenthesis around the star. To declare a variable to hold the above, use this:
- int (*p
)(char *);
+ int (*func_t
)(char *);
+
+Another trick is:
+ typedef int (*func_t)(char *);
+
+ int foo(char *x) {
+ printf("%s",x);
+ }
+
+
+ func_t p = foo;
+ return p("Narf!"
);
