77 The <STRONG>border</STRONG>, <STRONG>wborder</STRONG> and <STRONG>box</STRONG> routines draw a box around the
78 edges of a window. Other than the window, each argument
79 is a character with attributes:
81 <EM>ls</EM> - left side,
82 <EM>rs</EM> - right side,
83 <EM>ts</EM> - top side,
84 <EM>bs</EM> - bottom side,
85 <EM>tl</EM> - top left-hand corner,
86 <EM>tr</EM> - top right-hand corner,
87 <EM>bl</EM> - bottom left-hand corner, and
88 <EM>br</EM> - bottom right-hand corner.
90 If any of these arguments is zero, then the corresponding
91 default values (defined in <STRONG>curses.h</STRONG>) are used instead:
93 <STRONG>ACS_VLINE</STRONG>,
94 <STRONG>ACS_VLINE</STRONG>,
95 <STRONG>ACS_HLINE</STRONG>,
96 <STRONG>ACS_HLINE</STRONG>,
97 <STRONG>ACS_ULCORNER</STRONG>,
98 <STRONG>ACS_URCORNER</STRONG>,
99 <STRONG>ACS_LLCORNER</STRONG>,
100 <STRONG>ACS_LRCORNER</STRONG>.
102 <STRONG>box(</STRONG><EM>win</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>)</STRONG> is a shorthand for the following
103 call: <STRONG>wborder(</STRONG><EM>win</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>,</STRONG> <STRONG>0,</STRONG> <STRONG>0,</STRONG> <STRONG>0,</STRONG>
106 The <STRONG>hline</STRONG> and <STRONG>whline</STRONG> functions draw a horizontal (left to
107 right) line using <EM>ch</EM> starting at the current cursor posi-
108 tion in the window. The current cursor position is not
109 changed. The line is at most <EM>n</EM> characters long, or as
110 many as fit into the window.
112 The <STRONG>vline</STRONG> and <STRONG>wvline</STRONG> functions draw a vertical (top to
113 bottom) line using <EM>ch</EM> starting at the current cursor posi-
114 tion in the window. The current cursor position is not
115 changed. The line is at most <EM>n</EM> characters long, or as
116 many as fit into the window.
120 <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
121 All routines return the integer <STRONG>OK</STRONG>. The SVr4.0 manual
122 says "or a non-negative integer if <STRONG>immedok</STRONG> is set", but
123 this appears to be an error.
125 X/Open does not define any error conditions. This imple-
126 mentation returns an error if the window pointer is null.
128 Functions with a "mv" prefix first perform a cursor move-
129 ment using <STRONG>wmove</STRONG>, and return an error if the position is
130 outside the window, or if the window pointer is null.
134 <H2><a name="h2-NOTES">NOTES</a></H2><PRE>
135 The borders generated by these functions are <EM>inside</EM> bor-
136 ders (this is also true of SVr4 curses, though the fact is
139 Note that <STRONG>border</STRONG> and <STRONG>box</STRONG> may be macros.
143 <H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
144 These functions are described in the XSI Curses standard,
145 Issue 4. The standard specifies that they return <STRONG>ERR</STRONG> on
146 failure, but specifies no error conditions.
