Detailed Description

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:

 // 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
 }
