Cannot implicitly convert expression (&sbuf) of type char [1024] to IOREQ *

[Anders S via Digitalmars-d-learn]

Hi guys,

I want to write into a fifo pipe using write( ...)
Now a gather my data into my own struct IOREQ so in order to 
write I have to cast into an char buffer.

My problem in dlang is that it doesn't accept the casting (IOREQ 
*) I get:
Error: Cannot implicitly convert expression (&sbuf) of type char 
[1024] to IOREQ*

define FC_GETSTATUS 501;
typedef struct {
	SHORT	fc;			/* function code */
	SHORT	rs;			/* return code */
	INT	size;			       /* size of this request, including header */
	SHORT	src;			/* source */
	....
	INT	argv[1];		/* list of arguments */
} IOREQ;

int WritePipe(int fd, int mess, int argc)
{
   struct IOREQ * io; // my array of data
   char sbuf[1024];
   io = (IOREQ *)buf;      // Not accepted in dlang
   io.fc = FC_GETSTATUS;
   io.src = getpid();        // works

..... // add more data

   st = write(fd, sbuf, 1024);  //
   return st;
}
