# PetscViewerHDF5GetGroup
Get the current HDF5 group name (full path), set with `PetscViewerHDF5PushGroup()`/`PetscViewerHDF5PopGroup()`. 
## Synopsis
```
#include "petscviewerhdf5.h" 
PetscErrorCode PetscViewerHDF5GetGroup(PetscViewer viewer, const char path[], char *abspath[])
```
Not Collective


## Input Parameters

- ***viewer -*** the `PetscViewer` of type `PETSCVIEWERHDF5`
- ***path -*** (Optional) The path relative to the pushed group



## Output Parameter

- ***abspath -*** The absolute HDF5 path (group)





## Notes
If path starts with '/', it is taken as an absolute path overriding currently pushed group, else path is relative to the current pushed group.
`NULL` or empty path means the current pushed group.

The output abspath is newly allocated so needs to be freed.
