## wxFFileInputStream

This class represents data read in from a file. There are actually two such groups of classes: this one is based on wxFFile whereas wxFileInputStream is based in the wxFile class.

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

Derived from

wxInputStream
