that's true. argv[0] gives it relative to the cwd. this is going to
be a method in a library. using argv approach would require that I
have some sort of initialize method that I must then require the user
of the library to call very early in the program in an attempt to
cache the data before someone else changed the cwd. Design wise, this
locks me into something that is very similar in design to glut with
it's glutInit method. This just makes using the lib too tricky to > use.

I'm needing to find a way to get the path to where the actual
executable file resides using POSIX apis. For example:
foo is located at /usr/bin/foo
when I execute foo, I want it to print /usr/bin/foo no matter what
directory I'm in.
something that is equivalent to [nsBundle mainBundle] bundlePath]
any suggestions? please cc me directly.
Jaguar and above define _NSGetExecutablePath in the System framework.
It's a snap if you will be linking Foundation already, but if you don't
go that route
their is a straight C solution in sample code on Apple's site.
The solution they present is not portable to other unix flavors, but is
the most efficient
way for OSX.
I am unaware of a portable approach which does not insist you be called
first,
This one relies on exec stashing a copy of the executables path
immediately
after the trailing NULL of envp.

getpath.c.htm
I don't recall if it this path contains symlinks, if it does, a call to
realpath(3) will
normalize for you.
