N    * fflush function or to a file positioning function (fseek, fsetpos,
N    * rewind) discards any pushed-back characters. The extern _ARMABIal storage
N    * corresponding to the stream is unchanged.
N    * One character pushback is guaranteed. If the unget function is called too
N    * many times on the same stream without an intervening read or file
N    * positioning operation on that stream, the operation may fail.
N    * If the value of c equals that of the macro EOF, the operation fails and
N    * the input stream is unchanged.
N    * A successful call to the ungetc function clears the end-of-file
N    * indicator. The value of the file position indicator after reading or
N    * discarding all pushed-back characters shall be the same as it was before
N    * the characters were pushed back. For a text stream, the value of the file
N    * position indicator after a successful call to the ungetc function is
N    * unspecified until all pushed-back characters are read or discarded. For a
N    * binary stream, the file position indicator is decremented by each
N    * successful call to the ungetc function; if its value was zero before a
N    * call, it is indeterminate after the call.
N    * Returns: the character pushed back after conversion, or EOF if the
N    *          operation fails.
