defining a function pointer:  (*name)(); example,int (*strcmp_p)(const char *, const char*); Typedefs vastly simplifies things:typedef void (*func_p)(int, char *, ...); func_p ptr_to_func, *ptr_to_ptr_to_func, arr_of_func_ptrs[10];Assigning, from previous examples:strcmp_p = strcmp; or, using old-style syntax:strcmp_p = &strcmp;calling through pointer:int result = strcmp_p("foo", "bar");or old-style syntax:int result = (*strcmp_p)("foo", "bar");
