NAME
intrflush — enable or disable flush on interrupt
SYNOPSIS
#include <curses.h>
int intrflush(WINDOW *win, bool bf);
DESCRIPTION
The intrflush() function specifies whether pressing an interrupt key (interrupt, suspend or quit) will
flush the input buffer associated with the current screen. If bf is TRUE, pressing an interrupt key will
flush this input buffer. If bf is FALSE, pressing an interrupt key will not flush this input buffer. The
default for the option is inherited from the display driver settings. The win argument must refer to a
window associated with the current screen.
RETURN VALUE
Upon successful completion,
intrflush() returns OK. Otherwise, it returns ERR.
ERRORS
No errors are defined.
APPLICATION USAGE

System Interface Definitions, Issue 4, Version 2 specification (General Terminal Interface ).
