Functions

char* kbdhandle(int fd, char message[15], bool output);  //Returns the pressed key
int kbdinit();                                           //Inits the library
void kbddeinit(int kbdfd);                               //Closes the library
char* kbdscan(int kbdfd);                                //Scans for keypresses
int kbdver();                                            //Returns the library version

kbdver(); = returns the lib version
kbdinit(); = inits the lib and returns the keyboard fd handle
kbdscan(); = similar to WPAD_Scan(); but returns the raw message from the kbd, must be passed what kbd returned
kbdhandle(); = returns the charachter or code of what was pressed, fd is what kbdinit returned, message is what kbdscan returns, output is whether you want the full breakdown of the message
kbddeinit(); = closes the library, must be done before exit(0); or similar, must be passed what kbdinit returned

Examples :

int kbdfd = kbdinit();
char receivedmessage[15] = kbdscan(kbdfd);
char* pressed = kbdhandle(kbdfd, receivedmessage, false);
printf("%s was pressed\n", pressed);
kbddeinit(kbdfd);

Or more complicated :

int kbdfd = kbdinit();
printf("%s was pressed\n",kbdhandle(kbdfd,kbdscan(kbdfd), false);
kbddeinit(kbdfd);
