-\fBinstr\fR, \fBinnstr\fR, \fBwinstr\fR, \fBwinnstr\fR,
-\fBmvinstr\fR, \fBmvinnstr\fR, \fBmvwinstr\fR, \fBmvwinnstr\fR - get a string

+\fBwinnstr\fR,
+\fBmvinstr\fR,
+\fBmvinnstr\fR,
+\fBmvwinstr\fR,
+\fBmvwinnstr\fR \- get a string of characters from a \fBcurses\fR window
.SH SYNOPSIS
\fB#include <curses.h>\fR
-
+.sp
\fBint instr(char *str);\fR
.br
\fBint innstr(char *str, int n);\fR
.SH RETURN VALUE
All of the functions return \fBERR\fR upon failure,
or the number of characters actually read into the string.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+if the window parameter is null or the str parameter is null,
+a zero is returned.
+.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.
.SH NOTES
Note that all routines except \fBwinnstr\fR may be macros.
.SH PORTABILITY
-The XSI Curses
-error conditions \fBEILSEQ\fR and \fBEILOVERFLOW\fR associated with
-extended-level conformance are not yet detected (this implementation does not
-yet support XPG4 multi-byte characters).
SVr4 does not
document whether a length limit includes or excludes the trailing NUL.
.PP
In this case, the functions return the string ending at the right margin.
