## wxFFileOutputStream

This class represents data written to 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 SeekO() can seek beyond the end of the stream (file) and will thus not return wxInvalidOffset for that.

Derived from

wxOutputStream
