int delch(void); 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 y, 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 delch, mvdelch, and 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.
