@kirby Okay, here you go;

#include <stdio.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <unistd.h>

int main()
{
/* open file */
int fp = open("main.c", O_RDONLY);

/* get file stats */
struct stat s;
fstat(fp, &s);

char buffer[s.st_size];
ssize_t ignored = read(fp, buffer, s.st_size);
close(fp);

ignored = write(STDOUT_FILENO, buffer, sizeof(buffer));

}
