Hi again, still have problem. It works when using plain text but 
not like this:
(Hope you can identify my errors ;) )

import std.range, std.stdio, std.conv;
import core.stdc.string;
import core.stdc.stdio;
import core.sys.posix.sys.stat;
import core.sys.posix.unistd;
import core.sys.posix.fcntl;
import core.sys.posix.sys.stat;

extern (C) uint read(int, void *, uint);
extern (C) uint write(int, void *, ulong);

struct IOREQ {
  	short	fc;			/* function code */
  	short	rs;			/* return code */
  	int	size;			/* size of this request, including */
  	short	src;			/* source */
  	int	[1] argv;		/* list of arguments */
  };

     void main(string[] args) {
            //f;
            int fd = -1;
            IOREQ *io;
            fd = mkfifo("/Users/anders/pipes/8556",666 );
            char [1024]rbuf;
            char [1024]sbuf;
            sbuf = "You must use the cast keyword, the pointer to 
first element of an array is .ptr, and I think you meant sbuf:
                     io = cast(IOREQ *)sbuf.ptr;";

             io = cast (IOREQ *) sbuf;
             io.fc = 501;
             io.rs = 1234;
             io.src = 8556;
             writeln("\nio.fc :", io.fc);
            writeln("io.rs :", io.rs);
            writeln("\nio.src :", io.src);
             writeln ("\nio :",io);
            writeln("Skrev ", write(fd, cast (void*) sbuf, 
sbuf.length));
            writeln("läste ", read(fd, cast (void*) rbuf, 
sbuf.length));

            writeln("\nrbuf :", rbuf);
            io = cast(IOREQ *) rbuf;
            writeln("\nrio.fc :", io.fc);
            writeln("\nrio.rs :", io.rs);
            writeln("\nrio.src :", io.src);
            //unlink("/Users/anders/pipes/8556");

     }
