Description

The hline_set(), vline_set(), whline_set(), wvline_set() functions draw a line, in either the window stdscr or win starting at the current cursor position. The line is drawn using the character wch and is a maximum of n positions long, or as many as will fit into the window. If wch is a null pointer, the default horizontal or vertical character is used.

The mvhline_set(), mvvline_set(), mvwhline_set(), mvwvline_set() 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_set() draw horizontal lines proceeding towards the last column of the same line. The functions with names ending with vline_set() draw vertical lines proceeding towards the last column of the same line.

These functions do not change the position of the cursor.

Parameters

wch

Is the complex 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.
