Array of macros in c — is it possible

Question

I was wondering if it is possible to create something like an array of macros. I\'ve implemented the following code which works:

struct led_cmds_
{ 
    ioport_pi         


        

Answer 1

An array as tofro's answer is the way to go. However in cases that couldn't be solved simply with an array then there's another way with switch

#define SPECIFICPIN(X) (LED##X##_PIN)

void setpin(int pin, int value)
{
    switch (pin)
    {
    case 1:
        SPECIFICPIN(1) = value;
        doSomething(); // if needed
        break;
    case x: ...
    default: ...
    }
}
