# PetscObjectListRemoveReference
Calls `PetscObjectDereference()` on an object in the list immediately but keeps a pointer to the object in the list. 
## Synopsis
```
PetscErrorCode PetscObjectListRemoveReference(PetscObjectList *fl, const char name[])
```

## Input Parameters

- ***fl -*** the object list
- ***name -*** the name to use for the object





## Notes
Use `PetscObjectListAdd`(`PetscObjectList`,const char name[],NULL) to truly remove the object from the list

Use this routine ONLY if you know that the object referenced will remain in existence until the pointing object is destroyed


## Developer Note
This is to handle some cases that otherwise would result in having circular references so reference counts never got to zero


## See Also
