This is impossible if you require an answer that is always correct
regardless of circumstances.

The presence of hard links and symbolic links allows for many different
names for the "same" program. So "_the_ full path" might be ambiguous.

(snipped lots of good information)

Never mind that the full path at link time isn't likely to be the same
as the full path at run time.

Well, he did say "is linked" rather than "was linked", so I
assumed he wanted the current path of the current executable in
who's context the library is executing.

There isn't really a good, general way to find out. Most
people who want to know are asking for the wrong reasons
anyway. Usually when people ask "how do I find the location of
the program's exectuable" it's becuase they're Windows
programmers who think configuration files are stored in the
same directory as executables.

Under Unix that's most definitely _not_ where configuration
files go, so there shouldn't be any real need to know.
