MirOS Manual: curs_delch(3), delch(3), mvdelch(3), mvwdelch(3), wdelch(3)

curs_delch(3)       UNIX Programmer's Manual        curs_delch(3)


     delch, wdelch, mvdelch, mvwdelch - delete character under
     the cursor in a curses window


     #include <curses.h>

     int delch(void);
     int wdelch(WINDOW *win);
     int mvdelch(int y, int x);
     int mvwdelch(WINDOW *win, int y, int x);


     These routines delete the character under the cursor; all
     characters to the right of the cursor on the same line are
     moved to the left one position and the last character on the
     line is filled with a blank.  The cursor position does not
     change (after moving to y, x, if specified).  (This does not
     imply use of the hardware delete character feature.)


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


     Note that delch, mvdelch, and mvwdelch may be macros.


     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.
