int delch(void);

int mvdelch(int y, int x);

int mvwdelch(WINDOW *win, int y, int x);

int wdelch(WINDOW *win);

Description

The delch() and wdelch() functions delete the character at the current cursor position from stdscr and win, respectively. All remaining characters after cursor through to the end of the line are shifted one character towards the start of the line. The last character on the line becomes a space; characters on other lines are not affected.

The mvdelch() and mvwdelch() functions delete the character at the position specified by the x and y parameters; the former deletes the character from stdscr; the latter from win.

Parameters

y

Is the y (row) coordinate of the position of the character to be removed.

x

Is the x (column) coordinate of the position of the character to be removed.

win

Is a pointer to the window containing the character to be removed.

Return Values

On success, these functions return OK. Otherwise, they return ERR.

Errors

None.
