NAME

getbool - ask user to type boolean value

SYNOPSIS

#include <stdio.h>
#include <c.h>

int getbool (prompt,defalt);
char *prompt;
int defalt;

DESCRIPTION

Getbool is used to ask the user to type "yes" or "no". Prompt is a string containing a message which will be printed; the user types "yes", "y", etc., or "no", "n", etc. in response to the question. Getbool returns 1 if "yes" (etc.) is typed, 0 for "no". If the user types just a carriage return, then defalt is returned.

DIAGNOSTICS

The user is informed if his response is not valid (e.g. "maybe"), and the prompt-and-response cycle is repeated.

BUGS

There is no provision for an "escape" answer (e.g. "I don't care").
