mvinsnstr, mvwinsstr, mvwinsnstr - insert string before
cursor in a curses window

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.
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
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
X/Open defines no error conditions. In this implementation, if the
window parameter is null or the str parameter is null, an error is
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.
