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)))
