NAME

	CreateExtIO -- create an IORequest structure

SYNOPSIS

	ioReq = CreateExtIO(port,ioSize);
	struct IORequest *CreateExtIO(struct MsgPort *, ULONG);

FUNCTION

	Allocates memory for and initializes a new IO request block
	of a user-specified number of bytes. The number of bytes
	MUST be the size of a legal IORequest (or extended IORequest)
	or very nasty things will happen.

INPUTS

	port - an already initialized message port to be used for this IO
	       request's reply port. If this is NULL this function fails.
	ioSize - the size of the IO request to be created.

RESULT

	ioReq - a new IO Request block, or NULL if there was not enough memory

EXAMPLE

	if (ioReq = CreateExtIO(CreatePort(NULL,0),sizeof(struct IOExtTD)))
