Using execv() with PATH env variable

I'm writing a shell and I want to use execv() and search for the right directory through the $PATH environment variable (Yes, I know I can use execvp() and just pass the name of the file to it).

What I'm thinking about doing is getting a string from getenv("PATH"), breaking it down to separate paths then trying each one. But I was wondering if there is an easier way to do it?

I guess the question is: how does execvp() search for the right path?

Thanks!

What you described is exactly how execvp() searches the PATH. I don't think there's much point in reimplementing this yourself.
