Inheritance diagram for wxFFileOutputStream:This class represents data written to a file.
There are actually two such groups of classes: this one is based on wxFFile whereas wxFileOutputStream is based in the wxFile class.
Note that wxOutputStream::SeekO() can seek beyond the end of the stream (file) and will thus not return wxInvalidOffset for that.
