- If a given terminal doesn't support a video attribute that
- an application program is trying to use, <STRONG>curses</STRONG> may sub-
- stitute a different video attribute for it. The <STRONG>termattrs</STRONG>
- and <STRONG>term_attrs</STRONG> functions return a logical <STRONG>OR</STRONG> of all video
- attributes supported by the terminal using <EM>A</EM><STRONG>_</STRONG> and <EM>WA</EM><STRONG>_</STRONG> con-
- stants respectively. This information is useful when a
- <STRONG>curses</STRONG> program needs complete control over the appearance
