|-||Extracts information from a cchar_t value wcval|
|-||Stores the character attributes in the location pointed to by attrs|
|-||Stores the color-pair in the location pointed to by color_pair|
|-||Stores the wide-character string, characters referenced by wcval, into the array pointed to by wch.|
|When wch is a null pointer, the getcchar function does the following:|
|-||Obtains the number of wide characters pointed to by wcval|
|-||Does not change the data referenced by attrs or color_pair|
|The setcchar function initializes the location pointed to by wcval by using:|
|-||The character attributes in attrs|
|-||The color pair in color_pair|
|-||The wide-character string pointed to by wch. The string must be L\0 terminated, contain at most one spacing character, which must be the first.|
|Up to CCHARW_MAX-1 nonspacing characters may follow. Additional nonspacing characters are ignored.|
|The string may contain a single control character instead. In that case, no nonspacing characters are allowed.|
The opts argument is reserved for future use. Currently, an application must provide a null pointer as opts.
The wcval argument may be a value generated by a call to setcchar or by a function that has a cchar_t output argument. If wcval is constructed by any other means, the effect is unspecified.
When wch is a null pointer, getcchar returns the number of wide characters referenced by wcval.
When wch is not a null pointer, getcchar returns OK upon successful completion, and ERR otherwise.
Upon successful completion, setcchar returns OK. Otherwise, it returns ERR.
