# PetscDeviceContextView
View a `PetscDeviceContext` 
## Synopsis
```
#include <petscdevice.h> 
PetscErrorCode PetscDeviceContextView(PetscDeviceContext dctx, PetscViewer viewer)
```
Collective on `viewer`


## Input Parameters

- ***dctx -*** The `PetscDeviceContext`
- ***viewer -*** The `PetscViewer` to view `dctx` with (may be `NULL`)



## Notes
If `viewer` is `NULL`, `PETSC_VIEWER_STDOUT_WORLD` is used instead, in which case this
routine is collective on `PETSC_COMM_WORLD`.
