intrflush

The intrflush routine is used to flush output in tty on interrupt.

Syntax

   #include <curses.h>



   int intrflush(WINDOW *win, bool bf);

Parameters

bf: A Boolean expression.
win: An ignored parameter.

Return Values

OK: Successful completion.
ERR: An error occurred.

Description

If this option is enabled (bf is TRUE), intrflush() flushes all output in the terminal driver when an interrupt, quit, or suspend character is sent to the terminal. This increases interrupt reponse time but causes CURSES to lose track of what currently exists on the screen. Whether this option is enabled or disabled by default depends on the tty driver.




	NOTE: The `intrflush()` routine is a macro.

Implementation Considerations

Identical to XPG/3
