curs_clear(3) Library Functions Manual curs_clear(3) NAME curs_clear, clear, wclear, erase, werase, clrtobot, wclrtobot, clr- toeol, wclrtoeol - Clear all or part of a Curses window LIBRARY Curses Library (libcurses.a, libcurses.so) SYNOPSIS # include <curses.h> int clear(void); int wclear(WINDOW *win); int erase(void); int werase(WINDOW *win); int clrtobot(void); int wclrtobot(WINDOW *win); int clrtoeol(void); int wclrtoeol(WINDOW *win); STANDARDS Interfaces documented on this reference page conform to industry stan- dards as follows: clear, wclear, erase, werase, clrtobot, wclrtobot, clrtoeol, wclrtoeol: XPG4, XPG4-UNIX Refer to the standards(5) reference page for more information about in- dustry standards and associated tags. DESCRIPTION The erase and werase routines copy blanks to every position in the win- dow. The clear and wclear routines are similar to erase and werase but also call clearok. The result is that the screen is cleared completely on the next call to wrefresh for that window and repainted from scratch. The clrtobot and wclrtobot routines erase all lines below the cursor in the window. In addition, these routines erase the current line to the right of the cursor, including the character on which the cursor is po- sitioned. The clrtoeol and wclrtoeol routines erase the current line to the right of the cursor, including the character on which the cursor is posi- tioned. NOTES The header file curses.h automatically includes the header file stdio.h. Note that erase, werase, clear, wclear, clrtobot, and clrtoeol may be macros. RETURN VALUES Upon successful completion, these routines return OK; otherwise, they return ERR.
