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 four
routines with n as the last argument insert a leading sub-
string 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 ^-representation of the control character.
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.
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 XSI Curses error conditions EILSEQ and EILOVERFLOW
associated with extended-level conformance are not yet
detected (this implementation does not yet support XPG4
curses(3x), curs_clear(3x), curs_inch(3x).
