These routines return a string of <STRONG>wchar_t</STRONG> characters in
<EM>wstr</EM>, extracted starting at the current cursor position in
the named window. Attributes are stripped from the char-
acters. The four functions with <EM>n</EM> as the last argument
return a leading substring at most <EM>n</EM> bytes long (exclusive
of the trailing NUL). Transfer stops at the end of the
current line, or when <EM>n</EM> bytes have been stored at the
location referenced by <EM>wstr</EM>.
If the size <EM>n</EM> is not large enough to store a complete
character, an error is generated.
</PRE>
<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
Note that all routines except <STRONG>winnwstr</STRONG> may be macros.
</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
All routines return <STRONG>ERR</STRONG> upon failure. Upon successful com-
pletion, the *<STRONG>inwstr</STRONG> routines return <STRONG>OK</STRONG>, and the *<STRONG>innwstr</STRONG>
routines return the number of characters read into the
string.
Functions with a "mv" prefix first perform a cursor move-
ment using <STRONG>wmove</STRONG>, and return an error if the position is
outside the window, or if the window pointer is null.
