I assume you have used the address in the AT_SUN_EXECNAME aux
vector entry and then have read from /proc/<pid>/as at that offset
to get the executable's pathname.
This gives you a full pathname in most cases. If not, it is because
the command was executed using a relative pathname (e.g., "./foo ...").
In this case, if the process has not changed its current working
directory, you can use chdir("/proc/<pid>/cwd") and use getcwd(3C)
to get the path to the current directory of the process. Concatenating
them yields the full pathname.
That is how pmap does it.
If the process is statically linked, then you are totally out of luck.

Sorry, you can't have it unless you have a Solaris source license.
