Detailed Description

このクラスはファイルからのデータ読み込みを表しています。

There are actually two such groups of classes: this one is based on wxFile whereas wxFFileInputStream is based in the wxFFile class.

Note that wxInputStream::SeekI() can seek beyond the end of the stream (file) and will thus not return wxInvalidOffset for that.

Library:  wxBase

Category:  Streams
