curs_insstr(3X) curs_insstr(3X)
insstr, insnstr, winsstr, winsnstr, mvinsstr, mvinsnstr,
mvwinsstr, mvwinsnstr - insert string before cursor in a curses
window
#include <curses.h>
int insstr(const char *str);
int insnstr(const char *str, int n);
int winsstr(WINDOW *win, const char *str);
int winsnstr(WINDOW *win, const char *str, int n);
int mvinsstr(int y, int x, const char *str);
int mvinsnstr(int y, int x, const char *str, int n);
int mvwinsstr(WINDOW *win, int y, int x, const char *str);
int mvwinsnstr(WINDOW *win, int y, int x, const char *str, int
n);
These routines insert a character string (as many characters as
will fit on the line) before the character under the cursor. All
characters to the right of the cursor are shifted right with the
possibility of the rightmost characters on the line being lost.
The cursor position does not change (after moving to y, x, if
specified). The functions with n as the last argument insert a
leading substring of at most n characters. If n<=0, then the
entire string is inserted.
Special characters are handled as in addch.
All routines that return an integer return ERR upon failure and
OK (SVr4 specifies only "an integer value other than ERR") upon
successful completion, unless otherwise noted in the preceding
routine descriptions.
X/Open defines no error conditions. In this implementation, if
the window parameter is null or the str parameter is null, an
error is returned.
Functions with a “mv” prefix first perform a cursor movement
using wmove, and return an error if the position is outside the
window, or if the window pointer is null.
Note that all but winsnstr may be macros.
These functions are described in the XSI Curses standard, Issue
4, which adds const qualifiers to the arguments.
The Single Unix Specification, Version 2 states that insnstr and
winsnstr perform wrapping. This is probably an error, since it
makes this group of functions inconsistent. Also, no
implementation of curses documents this inconsistency.
