x-resource-name

x-resource-name is a variable defined in `C source code'.
Its value is

nil

Documentation:
The name Emacs uses to look up X resources.
`x-get-resource' uses this as the first component of the instance name
when requesting resource values.
Emacs initially sets `x-resource-name' to the name under which Emacs
was invoked, or to the value specified with the `-name' or `-rn'
switches, if present.

It may be useful to bind this variable locally around a call
to `x-get-resource'. See also the variable `x-resource-class'.
