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 cur-
sor. 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.
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.
