12. Create a FIFO in a C program

Describe how to create a FIFO in a C program using the `mkfifo` function.

#include<sys/types.h>
#include<stdlib.h>
#include<stdio.h>
#include<sys/stat.h>
main()
{
   const char *fifo_path = "/tmp/myfifo";
   if(mkfifo(fifo_path,0666)==-1)
   {
       perror("mkfifo");
       exit(EXIT_FAILURE);
   }
   return 0;
}

This creates a fifo named myfifo at tmp with read and write permissions for all users.
