48 \fBmvwinchnstr\fR \- get a string of characters (and attributes) from a \fBcurses\fR window
52 \fB#include <curses.h>\fR
54 \fBint inchstr(chtype *chstr);\fR
56 \fBint inchnstr(chtype *chstr, int n);\fR
58 \fBint winchstr(WINDOW *win, chtype *chstr);\fR
60 \fBint winchnstr(WINDOW *win, chtype *chstr, int n);\fR
62 \fBint mvinchstr(int y, int x, chtype *chstr);\fR
64 \fBint mvinchnstr(int y, int x, chtype *chstr, int n);\fR
66 \fBint mvwinchstr(WINDOW *win, int y, int x, chtype *chstr);\fR
68 \fBint mvwinchnstr(WINDOW *win, int y, int x, chtype *chstr, int n);\fR
71 These routines return a NULL-terminated array of \fBchtype\fR quantities,
72 starting at the current cursor position in the named window and ending at the
73 right margin of the window. The four functions with \fIn\fR as
74 the last argument, return a leading substring at most \fIn\fR characters long
75 (exclusive of the trailing (chtype)0).
76 Constants defined in \fB<curses.h>\fR can be used with the \fB&\fR (logical
77 AND) operator to extract the character or the attribute alone from any position
78 in the \fIchstr\fR [see \fBcurs_inch\fR(3X)].
80 All routines return the integer \fBERR\fR upon failure and an integer value
81 other than \fBERR\fR upon successful completion (the number of characters
82 retrieved, exclusive of the trailing 0).
84 X/Open Curses defines no error conditions.
85 In this implementation:
87 If the \fIwin\fP parameter is null, an error is returned,
89 If the \fIchstr\fP parameter is null, an error is returned,
91 Functions with a \*(``mv\*('' prefix first perform a cursor movement using
92 \fBwmove\fP, and return an error if the position is outside the window,
93 or if the window pointer is null.
95 Note that all routines except \fBwinchnstr\fR may be macros. SVr4 does not
96 document whether the result string is zero-terminated; it does not document
97 whether a length limit argument includes any trailing 0; and it does not
98 document the meaning of the return value.
100 These functions are described in the XSI Curses standard, Issue 4. It is no
101 more specific than the SVr4 documentation on the trailing 0. It does specify
102 that the successful return of the functions is \fBOK\fR.

106 Comparable functions in the wide-character (ncursesw) library are
