# PetscDeviceContextGetCurrentContext
Get the current active `PetscDeviceContext` 
## Synopsis
```
#include <petscdevice.h> 
PetscErrorCode PetscDeviceContextGetCurrentContext(PetscDeviceContext *dctx)
```
Not Collective


## Output Parameter

- ***dctx -*** The `PetscDeviceContext`



## Notes
The user generally should not destroy contexts retrieved with this routine unless they
themselves have created them. There exists no protection against destroying the root
context.


## Developer Notes
Unless the user has set their own, this routine creates the "root" context the first time it
is called, registering its destructor to `PetscFinalize()`.
