ncursesw-morphos/man/curs_inwstr.3x
Thomas E. Dickey 5ae2721913 ncurses 5.9 - patch 20121102
+ realign these related pages:
    curs_add_wchstr.3x
    curs_addchstr.3x
    curs_addstr.3x
    curs_addwstr.3x
  and fix a long-ago error in curs_addstr.3x which said that a -1
  length parameter would only write as much as fit onto one line
  (report by Reuben Thomas).
+ remove obsolete fallback _nc_memmove() for memmove()/bcopy().
+ remove obsolete fallback _nc_strdup() for strdup().
+ cancel any debug-rpm in package/ncurses.spec
+ reviewed vte-2012, reverted most of the change since it was incorrect
  based on testing with tack -TD
+ un-cancel the initc in vte-256color, since this was implemented
  starting with version 0.20 in 2009 -TD

.SH DESCRIPTION
These routines return a string of \fBwchar_t\fR characters in \fIwstr\fR,
extracted starting at the current cursor position in the named window.
Attributes are stripped from the characters.
The four functions with \fIn\fR as the last argument return a leading substring at most
\fIn\fR bytes long (exclusive of the trailing NUL).
Transfer stops at the end of the current line, or when \fIn\fR bytes have
been stored at the location referenced by \fIwstr\fR.
.PP
If the size \fIn\fR is not large enough to store a complete character,
an error is generated.
.SH NOTES
Note that all routines except
\fBwinnwstr\fR
may be macros.
.SH RETURN VALUE
All routines return
\fBERR\fR
upon failure. Upon
successful completion, the *\fBinwstr\fR
routines return
\fBOK\fR, and the *\fBinnwstr\fR
routines return the
number of characters read into the string.
.PP
Functions with a "mv" prefix first perform a cursor movement using
\fBwmove\fP, and return an error if the position is outside the window,
or if the window pointer is null.
