Headphone or mic detection connected via 3.5 mm jack linux - linux

Question

I have written a small program that informs when any headphone or mic is connected or not.
I provide a file path to identify, is there any way to know through a C program which file path is for mic or headphone?
Here is the program:
#include <linux/input.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <fcntl.h>
int main()
{
int fd = -1;
char name[256]= {'\0'};
struct input_event event;
/*On my system
/dev/input/event6 for headphone
/dev/input/event5 for mic
*/
if ((fd = open("/dev/input/event6", O_RDONLY)) < 0) {
perror("evdev open");
exit(1);
}
if(ioctl(fd, EVIOCGNAME(sizeof(name)), name) < 0) {
perror("evdev ioctl");
}
printf("The device name on path %s is === %s\n Now Plug in or Plug out the device\n",
argv[1],name);
// while(1)
{
read(fd, &event, sizeof(struct input_event));
printf("Event type is %d\n", event.type);
printf("Event code is %d\n", event.code);
printf("Event value is %d\n", event.value);
}
close(fd);
return 0;
}
Here i need to provide path in open, I want my program should identify the path of the mic or headphone. Is there anyway to do this?
It would be great to have some help.
thanks,
