reads the 明示するd number of bytes in the given sequence.
The return value 明示するs the number of bytes which have been
put into the sequence. A difference between nBytesToRead
and the return value 示すs that EOF has been reached. This means
that the method 封鎖するs until the 明示するd number of bytes are
利用できる or the EOF is reached.
Parameter aData
after the call, the byte sequence 含む／封じ込めるs the requested number
of bytes (or いっそう少なく as a 調印する of EOF).
C++ only : 公式文書，認める that for unbridged (e.g., in-過程)
calls, using the same sequence for repetive readBytes()-calls
can 耐える a 業績／成果 advantage. The callee can put the data
直接／まっすぐに into the sequence so that no 衝撃を和らげるもの reallocation is
necessary.
But this 持つ／拘留するs only when
neither 報知係 nor callee keep a second 言及／関連 to the same
sequence.
the sequence is pre-配分するd with the requested number of bytes.
the same sequence is 再使用するd ( 簡単に preallocationg a new
sequence for every call 耐えるs no advantage ).
the call is not 橋（渡しをする）d (e.g., betweeen different compilers
or different 過程s ).
If the same 'optimized' code runs against an interface in a different 過程,
there is an unnecessary memory 配分/deallocation (the out parameter
is of course NOT 輸送（する）d over the 関係), but this should
be ごくわずかの compared to a synchron call.
reads the 利用できる number of bytes, at 最大限
nMaxBytesToRead.
This method is very 類似の to the readBytes method, except that
it has different 封鎖するing behaviour.
The method 封鎖するs as long as at least 1 byte is 利用できる or
EOF has been reached. EOF has only been reached, when the method
returns 0 and the corresponding byte sequence is empty.
さもなければ, after the call, aData 含む／封じ込めるs the 利用できる,
but no more than nMaxBytesToRead, bytes.
Parameter aData
含む／封じ込めるs the data read from the stream.
Parameter nMaxBytesToRead
The 最大限 number of bytes to be read from this
stream during the call.
使用者s must の近くに the stream explicitly when no その上の
reading should be done. (There may 存在する （犯罪の）一味 言及／関連s to
chained 反対するs that can only be 解放（する）d during this call.
Thus not calling this method would result in a 漏れる of memory or
外部の 資源s.)
