.SH DESCRIPTION
|
|
These routines return a string of characters in \fIstr\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 characters long (exclusive of the trailing NUL).
|
|
.SH RETURN VALUE
|
|
All of the functions return \fBERR\fR upon failure,
|
|
or the number of characters actually read into the string.
|
|
.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 multibyte characters).
|
|
SVr4 does not
|
|
document whether a length limit includes or excludes the trailing NUL.
|
|
.PP
|
|
The ncurses library extends the XSI description by allowing a negative
|
|
value for \fIn\fR.
|
|
In this case, the functions return the string ending at the right margin.
|
|
