Or you need to maintain a mapping yourself. Hmm.

Well, I like to think I can just about handle free()ing the things which
are allocated, but I'm human so I'll always make mistakes. ;) However,
I'm only working with the API XRandR gives me, and that inherently works
with strings as monitor names/identifiers, not numbers.
What's irritating though is XRandR allows you to configure the
"ordering" of monitors---rather, their placement with respect to one
another. But that's wishy-washy with respect to ascertaining that
ordering. Take the following from my workstation here at home:
% xrandr -q
Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 8192 x 8192
VGA1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis)
477mm x 268mm
1920x1080 60.00*+
1600x1200 60.00
1680x1050 59.95
1280x1024 60.02
1440x900 59.89
1280x960 60.00
1280x800 59.81
1024x768 60.00
800x600 60.32 56.25
640x480 60.00
HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm
x 268mm
That's the ordering from xrandr itself, and you canm see it lists VGA1
first, despite the fact that it's technically right of HDMI1 (look at
the geometry strings!)
I'll see if I can enumerate the monitors based on some logical
positioning without the need to refer to them by name, but I fear it
might be a bit hit-and-miss when the "usefulness" of the API with
respect to referring to monitors by names is being thrown away.
Stand by...
