mvwdelch - delete character under the cursor in a
int wdelch(WINDOW *win);
int mvdelch(int y, int x);
int mvwdelch(WINDOW *win, int y, int x);
DESCRIPTION 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
x, if specified). (This does not imply use of the hardware delete character feature.)
RETURN VALUE All routines return the integer
ERR upon failure and an
OK (SVr4 specifies only "an integer value other than
ERR") upon successful completion.
NOTES Note that
mvwdelch may be macros.
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.
