InputStreamOverStream InputStreamOverStream InputStreamOverStream InputStreamOverStream Class


Provides a Windows Runtime input stream for an IStream base implementation.

The InputStreamOverStream, OutputStreamOverStream, and RandomAccessStreamOverStream classes are interop helpers to convert between the Windows Runtime stream types, which are natively asynchronous, and the Component Object Model (COM) IStream types, which are natively synchronous.

These helper classes make it easier for to reuse legacy code when you transition to the Windows Runtime stream types.


Close() Close() Close() Close()

Closes the current stream and releases system resources.

Returns an asynchronous byte reader object.

IBuffer IBuffer IBuffer IBuffer

The buffer into which the asynchronous read operation places the bytes that are read.

unsigned int UInt32 UInt32 UInt32

The number of bytes to read that is less than or equal to the Capacity value.

InputStreamOptions InputStreamOptions InputStreamOptions InputStreamOptions

Specifies the type of the asynchronous read operation.
