Detailed Description

(Deprecated) Wrapper of C file stream for input or output.

This simple wrapper does not check the validity of the stream.

Note

implements Stream concept

deprecated: This was only for basic testing in version 0.1, it is found that the performance is very low by using fgetc(). Use FileReadStream instead.
