nw::io::IOStream::Read Member Function

virtual s32 Read(
     void*            buf,
     u32 length
);

	Name	Description
out	buf	Pointer to the buffer where data to be read is stored. The alignment of this data must match the alignment obtained using the GetBufferAlign function.
in	length	Data size to be read. The alignment of this data must match the alignment obtained using the GetSizeAlign function.

Returns the number of bytes actually read if successful.

Returns a negative value error code if an error occurs during reading.
For details about the error codes that are returned, refer to the description of the concrete class.

Reads data from the stream (synchronous process).

Fails on ASSERT if the return value of the nw::io::IOStream::CanRead function is false.
This function blocks processing until the reading out of data has completed. You can use the asynchronous version of the function (nw::io::IOStream::ReadAsync) if the return value of the nw::io::IOStream::CanAsync function is true.
