40 \fBmvwinsnstr\fR - insert string before cursor in a \fBcurses\fR window
42 \fB#include <curses.h>\fR
44 \fBint insstr(const char *str);\fR
46 \fBint insnstr(const char *str, int n);\fR
48 \fBint winsstr(WINDOW *win, const char *str);\fR
50 \fBint winsnstr(WINDOW *win, const char *str, int n);\fR
52 \fBint mvinsstr(int y, int x, const char *str);\fR
54 \fBint mvinsnstr(int y, int x, const char *str, int n);\fR

58 \fBint mvwinsnstr(WINDOW *win, int y, int x, const char *str, int n);\fR
61 These routines insert a character string (as many characters as will fit on the
62 line) before the character under the cursor. All characters to the right of
63 the cursor are shifted right, with the possibility of the rightmost characters
64 on the line being lost. The cursor position does not change (after moving to
65 \fIy\fR, \fIx\fR, if specified). The four routines with \fIn\fR as the last
66 argument insert a leading substring of at most \fIn\fR characters. If
67 \fIn\fR<=0, then the entire string is inserted.
69 If a character in \fIstr\fR is a tab, newline, carriage return or
70 backspace, the cursor is moved appropriately within the window. A
71 newline also does a \fBclrtoeol\fR before moving. Tabs are considered
72 to be at every eighth column. If a character in \fIstr\fR is another
73 control character, it is drawn in the \fB^\fR\fIX\fR notation.
74 Calling \fBwinch\fR after adding a control character (and moving to
75 it, if necessary) does not return the control character, but instead
76 returns a character in the ^-representation of the control character.
78 All routines that return an integer return \fBERR\fR upon failure and OK (SVr4
79 specifies only "an integer value other than \fBERR\fR") upon successful
80 completion, unless otherwise noted in the preceding routine descriptions.
82 Note that all but \fBwinsnstr\fR may be macros.
84 These functions are described in the XSI Curses standard, Issue 4, which adds
85 const qualifiers to the arguments. The XSI Curses error conditions
86 \fBEILSEQ\fR and \fBEILOVERFLOW\fR associated with extended-level conformance
87 are not yet detected (this implementation does not yet support XPG4 multibyte
90 \fBcurses\fR(3X), \fBcurs_clear\fR(3X), \fBcurs_inch\fR(3X).
