curs_beep(3) Library Functions Manual curs_beep(3) NAME curs_beep, beep, flash - Curses bell and screen flash routines LIBRARY Curses Library (libcurses.a, libcurses.so) SYNOPSIS #include <curses.h> int beep(void); int flash(void); STANDARDS Interfaces documented on this reference page conform to industry stan- dards as follows: beep, flash: XPG4, XPG4-UNIX Refer to the standards(5) reference page for more information about in- dustry standards and associated tags. DESCRIPTION The beep and flash routines are used to alert the terminal user. The routine beep sounds the audible alarm on the terminal, if possible. If an audible alarm is not possible, the routine flashes the screen (visi- ble bell), if possible. The routine flash flashes the screen, and if that is not possible, sounds the audible alarm. If neither an audible or visual signal is possible, these routines pro- duce no results. Nearly all terminals have an audible signal (bell or beep), but only some can flash the screen. NOTES The header file curses.h automatically includes the header file stdio.h. RETURN VALUES These routines always return OK.
