DESCRIPTION
These functions modify the attributes of the drawn content on stdscr or on the specified window.The
chgat()
function sets the attributes of the next n characters
to attr and the color pair to
color. If n is negative or
larger than the remainder of the line, it gets truncated.
The
wchgat() is
the same as the chgat() function, excepting that the
attributes are changed in the window specified by
win.
The
mvchgat()
and
mvwchgat()
functions are the same as the chgat() and
wchgat() functions, respectively, excepting that
they operate from the position specified by y,
x.
These functions do not perform wrapping. They do not update the cursor position.
RETURN VALUES
The functions that return an int will return one of the following values:
OK- The function completed successfully.
ERR- An error occurred in the function.
