Function Documentation

int G_yes	(	const char *	question,
		int	dflt
	)

Ask a yes/no question.

This routine prints a question to the user, and expects the user to respond either yes or no. (Invalid responses are rejected and the process is repeated until the user answers yes or no.)
The default indicates what the RETURN key alone should mean. A default of 1 indicates that RETURN means yes, 0 indicates that RETURN means no. The question will be appended with ''(y/n) '', and, if default is not -1, with ''[y] '' or ''[n] '', depending on the default.

Parameters

[in]	question
[in]	dflt

Returns

0 for No

1 for Yes
