.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.
