how can i have the full pathname with C function

[cantubas]

in shell script unix I do
echo $(cd $(dirname "$name");pwd)/$(basename "$name")

is it possible in C??

escuse me for my bad english, I'm french

Exactly how is that different to this?

echo $name

I mean the 'cd' happens in a sub-shell, so the side-effect of that is lost.

$ pwd
/usr/bin
$ name="sh"
$ echo $(cd $(dirname "$name");pwd)/$(basename "$name")
/usr/bin/sh
$ echo $name
sh


do you anderstand??

So it's this then?

echo `pwd`/$name

Or were you hoping to get "/usr/bin/sh" even when the current directory isn't /usr/bin? This sounds exactly like the "which" command.

What other examples of pwd and $name do you have to worry about?

Stating the problem rather than your current answer would be a help as well.

i want a C function that can translate any relative name (like ../bin/sh) into absolute name (like /usr/bin/sh)

i want a C solution if it's possible
