frameset-compute-pos

frameset-compute-pos is a compiled Lisp function in `frameset.el'.

(frameset-compute-pos VALUE LEFT/TOP RIGHT/BOTTOM)

Return an absolute positioning value for a frame.
VALUE is the value of a positional frame parameter (`left' or `top').
If VALUE is relative to the screen edges (like (+ -35) or (-200), it is
converted to absolute by adding it to the corresponding edge; if it is
an absolute position, it is returned unmodified.
LEFT/TOP and RIGHT/BOTTOM indicate the dimensions of the screen in
pixels along the relevant direction: either the position of the left
and right edges for a `left' positional parameter, or the position of
the top and bottom edges for a `top' parameter.
