| Synopsis |
|
|
|
|
| IO arrays with boxed elements
|
|
| data IOArray i e |
An IOArray is a mutable, boxed, non-strict array in the IO monad.
The type arguments are as follows:
- i: the index type of the array (should be an instance of Ix)
- e: the element type of the array.
| Instances | |
|
|
| IO arrays with unboxed elements
|
|
| data IOUArray i e |
Mutable, unboxed, strict arrays in the IO monad. The type
arguments are as follows:
- i: the index type of the array (should be an instance of Ix)
- e: the element type of the array. Only certain element types
are supported: see Data.Array.MArray for a list of instances.
| Instances | |
|
|
| castIOUArray :: IOUArray ix a -> IO (IOUArray ix b) |
| Casts an IOUArray with one element type into one with a
different element type. All the elements of the resulting array
are undefined (unless you know what you're doing...).

| :: Handle | Handle to read from
| | -> IOUArray Int Word8 | Array in which to place the values
| | -> Int | Number of Word8s to read
| | -> IO Int | Returns: the number of Word8s actually
read, which might be smaller than the number requested
if the end of file was reached.
| | Reads a number of Word8s from the specified Handle directly
into an array.
