			...
	)

Requests an user name and a password.

This function waits until the user dismisses the dialog or responds. It's interruptible via vlc_interrupt. In that case, vlc_dialog_cbs.pf_cancel() will be invoked. If p_store is not NULL, the user will be asked to store the password or not.

Parameters

p_obj	the VLC object emitting the dialog
ppsz_username	a pointer to the user name provided by the user, it must be freed with free() on success

psz_default_username	default user name proposed
psz_title	title of the login dialog
psz_fmt	format string for the login message

Returns

< 0 on error, 0 if the user cancelled it, and 1 if ppsz_username and ppsz_password are valid.

		const char *	psz_action2,
		const char *	psz_title,
		const char *	psz_fmt,
			...
	)

Asks a total (Yes/No/Cancel) question.

This function waits until the user dismisses the dialog or responds. It's interruptible via vlc_interrupt. In that case, vlc_dialog_cbs.pf_cancel() will be invoked. The psz_cancel is mandatory since this dialog is always cancellable by the user.

Parameters

p_obj	the VLC object emitting the dialog
i_type	question type (severity of the question)
psz_cancel	text of the cancel button
