+ All routines return <STRONG>ERR</STRONG> upon failure. Upon successful completion, the
+ *<STRONG>inwstr</STRONG> routines return <STRONG>OK</STRONG>, and the *<STRONG>innwstr</STRONG> routines return the number
+ of characters read into the string.
+
+ X/Open defines no error conditions. This implementation returns an
+ error
+
+ <STRONG>o</STRONG> if the <EM>win</EM> parameter is null or
+
+ <STRONG>o</STRONG> if the <EM>wstr</EM> parameter is null, or
+
+ <STRONG>o</STRONG> if no characters could be read.
+
+ Functions prefixed with "mv" first perform cursor movement and fail if
+ the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries.
