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 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 win‐
dow. 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 posi‐
tion specified by x and y.
The functions with names ending with hline() draw horizontal lines pro‐
ceeding 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
