    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    Code:
    #include <stdio.h>
    #include <fcntl.h>
    #include <string.h>
    
    typedef int FLIES;
    
    int main (int argc, char *argv[]) {
    	char content[]="data";
    	FLIES away=open(argv[1],O_WRONLY | O_CREAT), x=1;
    
    	if (!(argv[1])) { puts("You didn't specify a filename."); return -1; }
    	if (write(away,content,strlen(content))<3) perror("write");
    	close(away);		
    	return 0;
    }
