[QnA] procfs: How to read the unresolved location of an executable?

[Martin Rodriguez Reboredo <yakoyoku@gmail.com>]

I have an MWE with a combined multi utils executable like BusyBox. I know I 
can use the arguments passed to deduct which name the executable was invoked 
with.

$ ln -s multi example

$ ./example # example should show in argv

I want to do the same with procfs but if I use `/proc/self/exe` it points out 
to the full path of multi instead of example's. Is there a way to know the 
location of example with procfs? My intention is to use this location with 
frameworks like Electron to find resource paths relative to the one of the 
invoking executable.
