Getch/Getchar
Part of TutorialFundamentals
Description
Get a character from the keyboard.
Example
import std.c.stdio; import std.stdio; void main() { char k; writefln("\nI'm going to ask you to press 10 keys (I promise it's painless).\n" "Certain keys don't count, but the whole alphabet is fair game.\n"); for(int i = 0; i < 10; i++) { version(Windows) { writef("Press key: %d\t", i); k = getch(); } version(linux) { writef("Press key (follow with return): %d\t", i); k = getchar(); } version(OSX) { // Unfortunately, merely using getchar() does not disable stdin and readline buffering. writef("Press key (follow with return): %d\t", i); k = getchar(); } writef("[%s]\t", k); /* print the character pressed */ writefln("[%d]\n", k); /* print ASCII code for key */ } writefln("\nThe End.\n"); }
