64.SH DESCRIPTION
65These functions return an array of complex characters in \fIwchstr\fR,
66starting at the current cursor position in the named window.
67Attributes (rendition) are stored with the characters.
68.PP
69The
70\fBin_wchnstr\fR,
71\fBmvin_wchnstr\fR,
72\fBmvwin_wchnstr\fR
73and
74\fBwin_wchnstr\fR
75fill the array
76with at most
77\fIn\fR
78\fBcchar_t\fR
79elements.
80.br
81.SH NOTES
82Note that all routines except
83\fBwin_wchnstr\fR
84may be
85macros.
86.PP
87Reading a line that overflows the array pointed to by
88\fIwchstr\fR
89with
90\fBin_wchstr\fR,
91\fBmvin_wchstr\fR,
92\fBmvwin_wchstr\fR
93or
94\fBwin_wchstr\fR
95causes undefined results. Therefore, the use of
96\fBin_wchnstr\fR,
97\fBmvin_wchnstr\fR,
98\fBmvwin_wchnstr\fR, or
99\fBwin_wchnstr\fR
100is recommended.
101.SH RETURN VALUES
102Upon successful completion, these functions return
103\fBOK\fR.
104Otherwise, they return
105\fBERR\fR.
106.SH PORTABILITY
107The XSI Curses defines no error conditions.
108This implementation checks for null pointers,
109returning ERR in that case.
