Function nix::unistd::execvp
pub fn execvp<S: AsRef<CStr>>(filename: &CStr, args: &[S]) -> Result<Infallible>Documentation
Replace the current process image with a new one and replicate shell PATH
searching behavior (see
exec(3)).
See ::nix::unistd::execve for additional details. execvp behaves the
same as execv except that it will examine the PATH environment variables
for file names not specified with a leading slash. For example, execv
would not work if “bash” was specified for the path argument, but execvp
would assuming that a bash executable was on the system PATH.
