On FreeBSD use AT_EXECPATH from ELF auxiliary vectors for getExecutablePath

Authored by emaste on Nov 13 2019, 11:50 AM.



/proc/curproc/file and the KERN_PROC_PATHNAME sysctl may not return the desired path if there are multiple hardlinks to the file.

Unfortunately we do not yet have a standard interface to obtain this in FreeBSD, but one will be added shortly. I will post a followup change to move to that based on FreeBSD version leaving this as a fallback, and eventually we can leave only that one.
