Rebase cause detached

[BohdanSomatic]

Hi i'm using code for rebase from example to preform git pull
but it cause detached head can any one explain why this happening
I would be really thankful for any piece of advice
-example code https://github.com/personalizedrefrigerator/libgit2/blob/main/examples/rebase.c
-my code
`

git_rebase *rebase = nullptr;

git_annotated_commit *fetched_head = nullptr;
git_reference *ref;
git_object *obj;

    git_revparse_single(&obj, repo_, "FETCH_HEAD");
    git_annotated_commit_lookup(&fetched_head, repo_, git_object_id(obj));
    git_object_free(obj);


checkErr(git_rebase_init(&rebase,
                         repo_,
                         NULL, // Rebase the current branch
                         NULL,
                         fetched_head,
                         NULL),
         "can't init rebase");

size_t operation_index = 0;
git_oid commit_oid;
git_rebase_operation *operation = NULL;
git_signature *signature = NULL;
checkErr(git_rebase_next(&operation, rebase),"rebase failed");

Rebase always does this, which is the same thing that git rebase on the command line does. If you pause the rebase processing (perhaps because you break or edit in the rebase script, or because you hit a conflict) then you will see that your HEAD is detached. Your head will be reattached, so to speak, when the rebase has been completed.
