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
