Consider the following code, which does not use a typedef:
int do_math(float arg1, int arg2) {
return arg2;
}
int call_a_func(int (*call_this)(float, int)) {
int output = call_this(5.5, 7);
return output;
}
int final_result = call_a_func(&do_math);This code can be rewritten with a typedef as follows:
typedef int (*MathFunc)(float, int);
int do_math(float arg1, int arg2) {
return arg2;
}
int call_a_func(MathFunc call_this) {
int output = call_this(5.5, 7);
return output;
}
int final_result = call_a_func(&do_math);ref:
