I have declared typedef void (*DoRunTimeChecks)();
How do I store that as a field in a struct? How do I assign it? How do I call the fn()?
Just put it in like you would any other field:
struct example {
int x;
DoRunTimeChecks y;
};
void Function(void)
{
}
struct example anExample = { 12, Function };
To assign to the field:
anExample.y = Function;
To call the function:
anExample.y();
#include <stdio.h>
typedef void (*DoRunTimeChecks)();
struct func_struct {
DoRunTimeChecks func;
};
void function()
{
puts("hello");
}
int main()
{
struct func_struct func_struct;
func_struct.func = function;
func_struct.func();
return 0;
}
