55 \fB\%mvwaddchnstr\fP \-
56 add a \fIcurses\fR character string to a window
59 \fB#include <curses.h>
61 \fBint addchstr(const chtype *\fIchstr\fP);
62 \fBint waddchstr(WINDOW *\fIwin\fP, const chtype *\fIchstr\fP);
63 \fBint mvaddchstr(int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP);
64 \fBint mvwaddchstr(WINDOW *\fIwin\fP, int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP);
66 \fBint addchnstr(const chtype *\fIchstr\fP, int \fIn\fP);
67 \fBint waddchnstr(WINDOW *\fIwin\fP, const chtype *\fIchstr\fP, int \fIn\fP);
68 \fBint mvaddchnstr(int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP, int \fIn\fP);
69 \fBint mvwaddchnstr(WINDOW *\fIwin\fP, int \fIy\fP, int \fIx\fP, const chtype *\fIchstr\fP, int \fIn\fP);
72 These functions copy the (null-terminated)
74 into the window image structure
75 starting at the current cursor position.
77 The four functions with \fIn\fP as the last
78 argument copy at most \fIn\fP elements,
79 but no more than will fit on the line.
80 If \fBn\fP=\fB\-1\fP then the whole array is copied,
81 to the maximum number of characters that will fit on the line.
83 The window cursor is \fInot\fP advanced.
84 These functions are faster than \fBwaddnstr\fP.
87 they do not perform checking
88 (such as for the newline, backspace, or carriage return characters),
90 they do not advance the current cursor position,
92 they do not expand other control characters to ^-escapes, and
94 they truncate the string if it crosses the right margin,
95 rather than wrapping it around to the new line.
97 All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
99 X/Open Curses does not specify any error conditions.
100 This implementation returns an error
102 if the \fIwin\fP parameter is null or
104 if the \fIwchstr\fP parameter is null.
106 Functions prefixed with \*(``mv\*('' first perform cursor movement and
110 is outside the window boundaries.
112 All functions except \fBwaddchnstr\fP may be macros.
114 These functions are described in X/Open Curses, Issue 4.
116 \fB\%curs_add_wchstr\fP(3X) describes comparable functions of the
118 library in its wide-character configuration
