It's using a C interface to assembly language to read from I/O port 0x60, which is mapped to the keyboard controller. These are old nonstandard Borland extensions that aren't really used anymore. In fact, only the 16-bit versions of the compiler supported these. As for what it does, it basically gets the value of the key being pressed and decides what to do based on that.
