Upon successful completion, the 83 *<STRONG>inwstr</STRONG> routines return <STRONG>OK</STRONG>, and the *<STRONG>innwstr</STRONG> routines return the number 84 of characters read into the string. 85 86 X/Open defines no error conditions. This implementation returns an 87 error 88 89 <STRONG>o</STRONG> if the <EM>win</EM> parameter is null or 90 91 <STRONG>o</STRONG> if the <EM>wstr</EM> parameter is null, or 92 93 <STRONG>o</STRONG> if no characters could be read. 94 95 Functions prefixed with "mv" first perform cursor movement and fail if 96 the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries. 97 98 99</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE> 100 All routines except <STRONG>winnwstr</STRONG> may be macros. 101 102 Each cell in the window holds a complex character (a spacing character 103 and zero or more non-spacing characters) together with attributes and 104 color. These functions store only the wide characters, ignoring 105 attributes and color. Use <STRONG>in_wchstr</STRONG> to return the complex characters 106 from a window. 107 108 Reading a line that overflows the array pointed to by <EM>wstr</EM> with <STRONG>inwstr</STRONG>, 109 <STRONG>mvinwstr</STRONG>, <STRONG>mvwinwstr</STRONG> or <STRONG>winwstr</STRONG> causes undefined results.
