winsdelln

curs_deleteln(3X)														 curs_deleteln(3X)

NAME

       deleteln, wdeleteln, insdelln, winsdelln, insertln, winsertln - delete and insert lines in a curses window

SYNOPSIS

       #include <curses.h>

       int deleteln(void);
       int wdeleteln(WINDOW *win);
       int insdelln(int n);
       int winsdelln(WINDOW *win, int n);
       int insertln(void);
       int winsertln(WINDOW *win);

DESCRIPTION

       The deleteln and wdeleteln routines delete the line under the cursor in the window; all lines below the current line are moved up one line.
       The bottom line of the window is cleared.  The cursor position does not change.

       The insdelln and winsdelln routines, for positive n, insert n lines into the specified window above the current line.  The n  bottom  lines
       are  lost.   For  negative n, delete n lines (starting with the one under the cursor), and move the remaining lines up.	The bottom n lines
       are cleared.  The current cursor position remains the same.

       The insertln and winsertln routines, insert a blank line above the current line and the bottom line is lost.

RETURN VALUE

       All routines return the integer ERR upon failure and an OK (SVr4 specifies only "an integer value other than ERR") upon successful  comple-
       tion.

PORTABILITY

       These  functions  are described in the XSI Curses standard, Issue 4.  The standard specifies that they return ERR on failure, but specifies
       no error conditions.

NOTES

       Note that all but winsdelln may be macros.

       These routines do not require a hardware line delete  or  insert  feature  in  the  terminal.   In  fact,  they	won't  use  hardware  line
       delete/insert unless idlok(..., TRUE) has been set on the current window.
