delch, wdelch, mvdelch, mvwdelch - delete character under the cursor in a curses window |
#include <curses.h> int delch(void); |
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. |
