int hline(chtype ch, int n);
int mvhline(int y, int x, chtype ch, int n);
int mvvline(int y, int x, chtype ch, int n);
int mvwhline(WINDOW *win, int y, int x, chtype ch, int n);
int mvwvline(WINDOW *win, int y, int x, chtype ch, int n);
int vline(chtype ch, int n);
int whline(WINDOW *win, chtype ch, int n);
int wvline(WINDOW *win, chtype ch, int n);

Description

The hline(), vline(), whline(), wvline() functions draw a horizontal or vertical line, in either the window stdscr or win starting at the current cursor position. The line is drawn using the character ch and is a maximum of n positions long, or as many as will fit into the window. If ch is 0 (zero), the default horizontal or vertical character is used.

The mvhline(), mvvline(), mvwhline(), mvwvline() functions are similar to the previous group of functions but the line begins at cursor position specified by x and y.

The functions with names ending with hline() draw horizontal lines proceeding towards the last column of the same line. The functions with names ending with vline() draw vertical lines proceeding towards the last column of the same line.

These functions do not change the position of the cursor.

Parameters

ch

Is the character used to draw the line.

n

Is the maximum number of characters in the line.

y

Is the y (row) coordinate for the start of the line.

x

Is the x (column) coordinate for the start of the line.

win

Is a pointer to a window.

Return Values

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

Errors

None
