setup_git_directory_gently contract question?

    Is the function setup_git_directory_gently supposed to change the
current working directory, or should it keep the initial one?
    What is the meaning of nongit_ok?

    Because if I use nongit_ok != NULL, but *nongit_ok == 1, this
function changes the current working directory to the top of the
worktree directory.

    Thanks,
    Ciprian Craciun.

    Or another question: how can I obtain the git directory (.git)
(absolute) path without updating the current working directory?

    Thanks,
    Ciprian Craciun.

It will change if it finds a worktree.

Setting it to a non null pointer prevents git from die() when no git
repository can be found.

It returns a directory prefix so that you can still know the original
current working directory. You can do as following to have current
directory "unchanged"

prefix = setup_git_directory_gently(&nongit_ok);
if (prefix) chdir(prefix)

   Thanks,
   Ciprian Craciun.
