insert string before cursor in a curses window 

Curses Function

SYNOPSIS

#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);

DESCRIPTION

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 four routines with n as the last argument insert a leading substring of at most n characters. If n<=0, then the entire string is inserted.

If a character in str is a tab, newline, carriage return or backspace, the cursor is moved appropriately within the window. A newline also does a clrtoeol() before moving. Tabs are considered to be at every eighth column. If a character in str is another control character, it is drawn in the ^X notation. Calling winch() after adding a control character (and moving to it, if necessary) does not return the control character, but instead returns a character in the the ^-representation of the control character.

RETURN VALUES

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.

NOTES

Note that all but winsnstr() may be macros.

PORTABILITY

These functions are described in the XSI Curses standard, Issue 4, which adds const qualifiers to the arguments. The XSI Curses error conditions EILSEQ and EILOVERFLOW associated with extended-level conformance are not yet detected (this implementation does not yet support XPG4 multi-byte characters).
