NAME
insstr, insnstr, winsstr, winsnstr, mvinsstr, mvinsnstr,
mvwinsstr, mvwinsnstr - insert string before cursor in a
curses window
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 charac-
ters 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 char-
acters 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.
RETURN VALUE
All routines that return an integer return ERR upon fail-
ure 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 implementa-
tion, 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 move-
ment using wmove, and return an error if the position is
outside the window, or if the window pointer is null.
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 Single Unix Specification, Version 2 states that
insnstr and winsnstr perform wrapping. This is probably
an error, since it makes this group of functions inconsis-
tent. Also, no implementation of curses documents this
inconsistency.
