* \brief KFile interface over a FIFO buffer.
|
||
|
|
*
|
||
|
|
* Convenient way to push data into a FIFO using the KFile interface.
|
||
|
|
* For example, it's possible to read from a serial port and put the characters
|
||
|
|
* into a fifo:
|
||
|
|
* \code
|
||
|
|
* // serial reader process
|
||
|
|
* {
|
||
|
|
* // other stuff here...
|
||
|
|
* kfile_read(&ser_port.fd, buffer, sizeof(buffer));
|
||
|
|
* kfile_write(&kfifo.fd, buffer, sizeof(buffer));
|
||
|
|
* // ...
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* // controller process
|
||
|
|
* {
|
||
|
|
* //...
|
||
|
|
* kfile_read(&kfifo.fd, buffer2, sizeof(buffer2));
|
||
|
|
* // use read data
|
||
|
|
* }
|
||
|
|
* \endcode
