[C/C++] getting keyboard input

[anthonycara]

both getchar() and getch() wait for input from the keyboard. is there any way i can just check if there is a keypress, and if not, continue thorugh a loop?

like, for instance, INKEY$ in BASIC or GETKEY on the TI83. :pinch:

it was asked before, the best way to go is getche() i guess (declared in conio.h)

getch() would be the appropriate function to use, since it doesn't echo back to the screen. Just put getch() into a while(true) {} loop and exit it when appropriate for your program.

The function kbhit returns true if there is a character waiting, which you can then retrieve with getch or getche. If you wanted it to operate like described, then you could create a function something like the following:

char GetKey(void){
 ?if(kbhit()){
 ? ?return getch();
 ?}else{//(kbhit())
 ? ?return 0;
 ?}//endif(kbhit())
}

thanx it works :)

im not that clear on how ti works, though.... is kbhit() a representation of the keyboard buffer?

[WetWired]

It's just another function in conio.h that checks the keyboard buffer for data. I returns true if there is data, and false if there is not.
