DESCRIPTION

-       These routines return a string of wchar_t characters in wstr, extracted
-       starting   at   the  current  cursor  position  in  the  named  window.
-       Attributes are stripped from the characters.  The four functions with n
-       as  the  last  argument return a leading substring at most n bytes long
-       (exclusive of the trailing NUL).  Transfer stops at the end of the cur-
-       rent  line, or when n bytes have been stored at the location referenced
-       by wstr.
+       These routines return a string of  wchar_t  wide  characters  in  wstr,
+       starting at the current cursor position in the named window.
 
-       If the size n is not large enough to store  a  complete  character,  an
-       error is generated.
+       The  four  functions  with  n  as  the  last  argument return a leading
+       substring at most n characters long (exclusive of  the  trailing  NUL).
+       Transfer  stops  at  the  end of the current line, or when n characters
+       have been stored at the location referenced by wstr.

NOTES

-       Note that all routines except winnwstr may be macros.
+       If the size  n  is  not  large  enough  to  store  a  complete  complex
+       character, an error is generated.

RETURN VALUE

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

NOTES

+       All routines except winnwstr may be macros.
+
+       Each  cell in the window holds a complex character (a spacing character
+       and zero or more non-spacing characters) together with  attributes  and
+       color.   These  functions  store  only  the  wide  characters, ignoring
+       attributes and color.  Use in_wchstr to return the  complex  characters
+       from a window.
+
+       Reading a line that overflows the array pointed to by wstr with inwstr,
+       mvinwstr, mvwinwstr or winwstr causes  undefined  results.   Therefore,
+       the use of innwstr, mvinnwstr, mvwinnwstr, or winnwstr is recommended.
