How do I find the location of the executable in C? [duplicate]

Answer 1

I would

1) Use the basename() function: http://linux.die.net/man/3/basename
2) chdir() to that directory
3) Use getpwd() to get the current directory

That way you'll get the directory in a neat, full form, instead of ./ or ../bin/.

Maybe you'll want to save and restore the current directory, if that is important for your program.
