rendition from a <STRONG>cchar_t</STRONG> argument. When <EM>wch</EM> is not a null
pointer, the <STRONG>getcchar</STRONG> function does the following:
- - Extracts information from a <STRONG>cchar_t</STRONG> value <EM>wcval</EM>
+ <STRONG>o</STRONG> Extracts information from a <STRONG>cchar_t</STRONG> value <EM>wcval</EM>
- - Stores the character attributes in the location
- pointed to by <EM>attrs</EM>
+ <STRONG>o</STRONG> Stores the character attributes in the location
+ pointed to by <EM>attrs</EM>
- - Stores the color-pair in the location pointed to by
- <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
+ <STRONG>o</STRONG> Stores the color-pair in the location pointed to by
+ <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
- - Stores the wide-character string, characters refer-
- enced by <EM>wcval</EM>, into the array pointed to by <EM>wch</EM>.
+ <STRONG>o</STRONG> Stores the wide-character string, characters refer-
+ enced by <EM>wcval</EM>, into the array pointed to by <EM>wch</EM>.
When <EM>wch</EM> is a null pointer, the <STRONG>getcchar</STRONG> function does the
following:
- - Obtains the number of wide characters pointed to by
- <EM>wcval</EM>
+ <STRONG>o</STRONG> Obtains the number of wide characters pointed to by
+ <EM>wcval</EM>
- - Does not change the data referenced by <EM>attrs</EM> or

+ <STRONG>o</STRONG> Does not change the data referenced by <EM>attrs</EM> or
+ <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
The <STRONG>setcchar</STRONG> function initializes the location pointed to
by <EM>wcval</EM> by using:
- - The character attributes in <EM>attrs</EM>
+ <STRONG>o</STRONG> The character attributes in <EM>attrs</EM>
- - The color pair in <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
+ <STRONG>o</STRONG> The color pair in <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
- - The wide-character string pointed to by <EM>wch</EM>. The
- string must be L'\0' terminated, contain at most one
- spacing character, which must be the first.
+ <STRONG>o</STRONG> The wide-character string pointed to by <EM>wch</EM>. The
