# PetscObjectGetTabLevel
Gets the number of tabs that `PETSCVIEWERASCII` output for that object uses 
## Synopsis
```
#include "petscsys.h"    
PetscErrorCode PetscObjectGetTabLevel(PetscObject obj, PetscInt *tab)
```
Not Collective


## Input Parameter

- ***obj -*** any PETSc object, for example a `Vec`, `Mat` or `KSP`. Thus must be
cast with a (`PetscObject`), for example,
`PetscObjectGetTabLevel`((`PetscObject`)mat,&tab);



## Output Parameter

- ***tab -*** the number of tabs





## Note
This is used to manage the output from options that are embedded in other objects. For example
the `KSP` object inside a `SNES` object. By indenting each lower level further the hierarchy of objects
is very clear.
