Is this bsearch call portable?

Is the following call to bsearch portable?  Note that 's' is the
key to be searched and is a pointer to 'char' whereas 'fun' is an 
array of 'FUN'. Also note that the function 'funcmp' uses only the 
string 'fun_name' for comparison. 

(I have not used casts in call to bsearch since I am using prototypes).

----------------------
char s[] = "fun2";

     pfun = (FUN *) bsearch (&s, fun, nfun, sizeof (FUN), funcmp);
----------------------

DECLARATIONS of variables used above.

typedef struct {
  char *fun_name;
  double (*fun_ptr) (double);
} FUN;

FUN  fun[] = {{"fun1",     fun1},
              {"fun2",     fun2},
};

int  nfun = sizeof (fun) / sizeof (FUN);
FUN  *pfun;

/*===========================================================================*/

int   funcmp (void *p1, void *p2)
{
	return (strcmp (((FUN *) p1)->fun_name, ((FUN *) p2)->fun_name));
}

Thanks.
