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
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
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.
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.
