mh-display-color-cells

mh-display-color-cells is a Lisp function in `mh-compat.el'.

(mh-display-color-cells &optional DISPLAY)

Return the number of color cells supported by DISPLAY.
This function is used by XEmacs to return 2 when `device-color-cells'
or `display-color-cells' returns nil. This happens when compiling or
running on a tty and causes errors since `display-color-cells' is
expected to return an integer.
