33 * \brief KFile interface over a FIFO buffer.
35 * Convenient way to push data into a FIFO using the KFile interface.
36 * For example, it's possible to read from a serial port and put the characters
39 * // serial reader process
41 * // other stuff here...
42 * kfile_read(&ser_port.fd, buffer, sizeof(buffer));
43 * kfile_write(&kfifo.fd, buffer, sizeof(buffer));
47 * // controller process
50 * kfile_read(&kfifo.fd, buffer2, sizeof(buffer2));
